- `filteredSubscriptions` was running the filter code whether or not it actually required filtering, because the `!subscriptionFilter` logic is placed in the predicate. While it is a clean one-liner, it is slow when the subs list is huge.
- While at it, moved the code into `getSubscriptionSection` to isolate things.
- The sidebar was resolving the entire subs list, which is super slow for a list of 500+. Since we now have a "Manage Subscriptions" page, just batch-resolve the N visible subs.
- TODO: the code should probably be moved from 'app' to 'sideNavigate'.
## Issues
1. We were manually adding `selectLanguage(state)` as a prop to components used in Settings Page to trigger a render. Flaws:
- Unclear that the unused prop is just to trigger a render.
- Manually adding on a case-by-case basis will break over time, especially when language can now be changed outside of the Settings Page.
2. The translation file fetching is delayed and also takes time, so the GUI will end up having mixed strings on F5, depending on when the fetch completed.
## Approach
Make the app wrapper have a key that's tied to the language and translation data, so the entire app renders when language changes. Seems like a common design in most apps.

## Issue
If you are already at the homepage and you click the "Home" or "Odysee" logo again, the entire page reloads, causing the whole startup sequence to re-run (lots of fetches).
This can be annoying when not intended (e.g. clicked too many times), as startup is slow for some and we also lose non-persistent Redux data (for debugging).
I believe the requirement was just to reload the homepage tiles, as they might be showing stale ones after a while. A full reload was the quick-and-easy fix.
## Approach
Best not to touch the complicated `ClaimTilesDiscover`, so just clear the search cache key in this scenario. `ClaimTilesDiscover` will then pick this up and perform a new `claim_search`.
`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).
## Behavioral changes
- Moved Notifications to the top for mobile.
- Added separate lines between sections.
## Code changes
The array method is too restrictive (hard to move things with display logic around). It's also hard to read.
Instead of trying to populate an array, just directly populate the return tree. Added `getLink` to make things readable. It's now easier to see the sections in a glance.
* add gdpr support
* only run on production
* testing implementation
* just needs last touches then ready
* ready for merge
* add cookies to sidebar
* hide button when secureprivacy not available
* switch over to loading script as a react hook
* conditionally add secureprivacy script
* save gdpr status on session
* better design
* Exclude default homepage data at compile time
The youtuber IDs alone is pretty huge, and is unused in the `CUSTOM_HOMEPAGE=true` configuration.
* Remove Desktop items and other cleanup
- Moved constants out of the component.
- Remove SIMPLE_SITE check.
- Remove Desktop-only items
* Sidebar: limit subscription and tag section
## Issue
Too slow for huge lists
## Change
Limit to 10 initially, and load everything on "Show more"
* Fix makeSelectThumbnailForUri
- Fix memo
- Expose function to extract directly from claim if client already have it.
- [x] (6332) The IntersectionObserver method of lazy-loading loads cached images visibly late on slower devices. Previously, it was also showing the "broken image" icon briefly, which we mended by placing a dummy transparent image as the initial src.
- Reverted that ugly transparent image fix.
- Use the browser's built-in `loading="lazy"` instead. Sorry, Safari.
- [x] Size-optimization did not take "device pixel ratio" into account.
- When resizing an image through the CDN, we can't just take the dimensions of the tag in pixels directly -- we need to take zooming into account, otherwise the image ends up blurry.
- Previously, we quickly disabled optimization for the channel avatar in the Channel Page because of this. Now that we know the root-cause, the change was reverted and we now go through the CDN with appropriate sizes. This also improves our Web Vital scores.
- [x] Size-optimization wasn't really implemented for all ChannelThumbnail instances.
- The CDN-optimized size was hardcoded to the largest instance, so small images like sidebar thumbnails are still loading images that are unnecessarily larger.
- There's a little-bit of hardcoding of values from CSS here, but I think it's a ok compromise (not something we change often). It also doesn't need to be exact -- the "device pixel ratio" calculate will ensure it's slightly larger than what we need.
- [x] Set `width` and `height` of `<img>` to improve CLS.
- Addresses Ligthhouse complaints, although technically the shifting was addressed at the `ClaimPreviewTile` level (sub-container dimensions are well defined).
- Notes: the values don't need to be the final CSS-adjusted sizes. It just needs to be in the right aspect ratio to help the browser pre-allocate space to avoid shifts.
- [x] Add option to disable lazy-load Channel Thumbnails
- The guidelines mentioned that items that are already in the viewport should not enable `loading="lazy"`.
- We have a few areas where it doesn't make sense to lazy-load (e.g. thumbnail in Header, channel selector dropdown, publish preview, etc.).
