Props: either use primitives, stable references or memoized objects to reduce renders. This update will simplify the existing `areEqual`. It is still needed though as some props are hard to memoize from where they are called, or should simply be ignore.
## Ticket
Part of "#385 Defer api.odysee.com calls to their respective pages / install new"
## Change
Pull out `notification/categories` from `doNotificationList` and fetch it in Notifications Page. I don't there there are other places that need it for now.
## Repro
- Do a search like "Test" and filter to "Channels Only".
- Follow a bunch @test channels
- Unfollow any one of them. All of them gets unfollowed.
## Notes
The change in b9fc9b63 to compare the lower-case channel name probably made it even worse, since "@TeSt" would be removed too.
## Change
Not sure why channel name was used in the first place ... perhaps it was to cover canon vs perm uri?
Anyway, comparing uri makes more sense, so doing that instead.
Was trying to save one event listener in the previous implementation and rely on other redux state-changes to spark a GUI update, but turns out there are scenarios where nothing is updated and the "offline" nag is stuck on screen.
## Change
Do it properly using the event listeners. The nag should now update promptly.
Changing the string means it will stay in English until retranslated. Reverting so that it can re-use existing translated database.
I don't think there is a clash in the `followingCount` variable, so the change was probably unnecessary.
## Issue
Apparently, a user is experiencing 423 locked errors from the server, which should not happen given the locking mechanism plus the user wasn't trying to do concurrent uploads.
## Fix
Anyway, fix the Resume button so that at least they can try to resume.

* Bump page size back to 50
## Issue
The ad tile causes a layout shift on certain screen/zoom, pushing CLS from green to red.
## Change
- Do replacement instead of insertion.
- Fixed "null lastCard" flow warning instead of suppressing it.
## Issue
https://www.notion.so/Performance-Fixes-927f825a5d674bd09323830be1d263af#1beab2fee011421492b56b88f68681a3
We currently lazy-load the tiles in the category sections (but not the sections themselves, because we want to retain scroll position on Back action). This puts gray placeholders until the section is visible on screen. which turns out to be quite expensive, because the placeholders are animated, so we have a perpetual animation in the background after the homepage loads + user did not scroll.
## Change
Just disable the barely-noticeable animation for now.
There are alternatives, but probably not worth polluting the code with:
- Just like the thumbnails, use intersection observer to decide when to animate.
- Find solution to the "lazy load section + need to retain scroll position".

Now that we have a dedicated chromecast button, we don't need to hack Chrome's default cast button to appear on top of vjs-mobile-ui. The hack no longer works anyway, since the CSS exposure has been deprecated around mid 2020 -- it is still available, but its abilities has become less and less.
- The graphic was meant to be 50% of the card width, but was squished.
- Try to reduce scrolling by making everything fit in a 100% zoom on a 1080p screen.
The previous version was trying to fetch an optimized image with the exact size required, but the URL given was pre-optimized, so it wasn't working correctly. The additional work is also slow (seems to lock up mobile a bit), and since it wasn't functional, just removed it entirely.
It will be easier to just pre-reduce the image size to something suitable for a 1080p screen (the most common screen size at the moment).
As noted in a comment, we need to be careful when adding props to `VideoJs` to avoid renders.
Used primitive strings (title, channelName) instead of passing the entire `claim`, which could have its reference invalidated.
## Ticket
426
## Issue
Currently, we check if we have any existing claims with the same name when uploading, i.e. "lbry://<name>". It does not include claims that you are still uploading, so you might end up with duplicate claims.
In the ticket, there is also the issue of 2 uploads sharing the same slot, causing the progress indicator to jumpy between the uploads. That has been fixed by using a guid instead of using `name`.
## Aside
I think there is another request to allow the same name but on different channel ... next time, next time ....
- Using `selectIsSubscribedForUri` instead, because the given uri is in Canon while the subscription list is in Permanent, so the result was always `false`.
- More css consolidation.
- More size and padding restoration (it wasn't 445's main intention to change sizes).
- Handle padding for mobile to hopefully make everything fit, especially for Playlists. We'll need an overflow menu to truely fix this for all screens.
## Scenario
`selectHasUnclaimedRefereeReward` updated --> `AppRouter` re-render --> `dynamicRoutes` regenerates (re-mounts) list of `DiscoverPage`s
## Fix
I think `selectHasUnclaimedRefereeReward` can be moved elsewhere and would solve the problem, but avoided that since I'm not familiar with rewards enough to do minimal testing.
Memoize the Category Page routes instead.
`GetLinksData` is somewhat expensive. The value won't change until user changes the window size or selects another homepage.
As we can't call an `effect` within a `memo`, we had to extract out `isLargeScreen` as an input parameter, which is fine as it makes `GetLinksData` more functional (functional programming).
## Issues
- So many `!important` overrides that makes it hard to customize.
- Weird "813px max-width" check -- it feels random, plus does not adjust accordingly to zoom-levels.
- The button text is not always vertically centered for all layout and zoom-levels because it is being centered using hardcoded margins.
- The 2 popups don't have consistent fonts and styling, plus their customizations are all over the place.
## Changes
- Try to remove as many unnecessary "!important" as possible. Adding specificity is sufficiently, and won't block other customizations.
- Try using `rem` instead of hardcoded margins. The icons/text/margin should resize accordingly per zoom-levels.
- I didn't replicate the "813px max-width" media check. If it is really necessary, please use `vjs-layout-*` to customize them instead.
- Consolidate the 2 popup menu customizations.
Each button should have the same touch area and roughly the same left-right margins. Currently, the Theater Button (or the Chromecast button) looks too far from Speed and too close from Autoplay. They should be evenly-spaced.
* Upload: fix redux key clash
## Issue
`params` is the "final" value that will be passed to the SDK and `channel` is not a valid argument (it should be `channel_name`). Also, it seems like we only pass the channel ID now and skip the channel name entirely.
For the anonymous case, a clash will still happen when since the channel part is hardcoded to `anonymous`.
## Approach
Generate a guid in `params` and use that as the key to handle all the cases above. We couldn't use the `uploadUrl` because v1 doesn't have it.
The old formula is retained to allow users to retry or cancel their existing uploads one last time (otherwise it will persist forever). The next upload will be using the new key.
* Upload: add tab-locking
## Issue
- The previous code does detect uploads from multiple tabs, but it was done by handling the CONFLICT error message from the backend. At certain corner-cases, this does not work well. A better way is to not allow resumption while the same file is being uploading from another tab.
- When an upload from 1 tab finishes, the GUI on the other tab does not remove the completed item. User either have to refresh or click Cancel. Clicking Cancel results in the 404 backend error. This should be avoided.
## Approach
- Added tab synchronization and locking by passing the "locked" and "removed" information through `localStorage`.
## Other considered approaches
- Wallet sync -- but decided not to pollute the wallet.
- 3rd-party redux tab syncing -- but decided it's not worth adding another module for 1 usage.
* Upload: check if locked before confirming delete
## Reproduce
Have 2 tabs + paused upload
Open "cancel" dialog in one of the tabs.
Continue upload in other tab
Confirm cancellation in first tab
Upload disappears from both tabs, but based on network traffic the upload keeps happening.
(If upload finishes the claim seems to get created)
* Settings Page: add warning for unsaved settings
## Issue
When entering Settings Page, sync-loop is disable until user exist Settings Page. If browser is closed, changes will be lost.
## Change
Add the usual browser-level modal popup.
Note that all modern browsers have stopped supporting customized messages, but I still left the message there for clarity. Tried to use our own toast for it, but the handler locks all GUI until it is serviced.
* app: remove unused props
* app: use lighter selectors
When all we need is to know if something exists or their count, use the ID version instead of the url/claim version to avoid the heavy transformation.
