## Issue
Closes 5721: Publish-Preview updates
## Changes
(1) Match the recent "incognito" change that sets the channel to `undefined` via `updatePublishForm`. This change would also cover `null` -- I don't think it's being used to represent something else, so showing "Anonymous" for `null` should be fine.
(2) Added channel icons, so it'll be more obvious to the user if they accidentally selected the wrong channel.
## Issue
Closes 5687: Ensure post mode has no text limit
## Changes
- `type="markdown"` can now have unlimited length if clients don't define `textAreaMaxWidth`.
- The internal default limit of 2000 is narrowed down to `type=textarea`.
## Issue
Closes 3661: Autoplay + Related go into loops ( infinite ) sometimes
## GUI
Push the actual "next" item into the top of the list.
## History search
1. Skip if the next item is itself.
2. The URL stored in the history comes in various forms, so a direct comparison won't work.
- There's also a weird case where the URL differs by just a little (p.09 vs p-09), but with the same claim ID:
lbry://vacuum-tube-computer-p.09-–-building#5212bc8bc63c373e2bf1ebc5b765595ed7b6514d
lbry://vacuum-tube-computer-p-09-–-building#5212bc8bc63c373e2bf1ebc5b765595ed7b6514d
Check the claim_id as well to cover cases like these.
## Issue
Closes 5537: Allow youtube sync new pass language to api
## Notes
- Default language for the selector comes from browser (`navigator.language`)
## Changes
- Restore original code for how Volume and Mute is restored.
- Playback rate will be only change that gets "re-restored" in "loadedmetadata".
## Issue
5513: Video-setting persistence broken
## Notes
- Per videojs recommendation, the setting-restoration should be done after the video has been loaded, so the action was moved to `loadedmetadata`. This fixed the volume slider problem, and should have fixed the playbackRate too.
- For playbackRate, there is another special case where it gets reset to 1 (refer to comments in code).
## Issue
Closes 4936: Don't process markdown formatting as lbry:// url previews
## Approach
Preamble:
- We want to convert plain `https://lbry.tv/befreeonlbry` to an embed, but not `[blah](https://lbry.tv/befreeonlbry)`.
- At the markdown/remark level, both formats resolve to the same node type, having a `link` and a `text`, with the 'text' being auto-filled with the `href` if there is no label.
Fix by assuming the link is the non-labelled format if the `text` is the same as `href`.
This opens up one corner-case that we can't handle, which is when the user explicitly set the label using the href, e.g. `[https://lbry.tv/befreeonlbry](https://lbry.tv/befreeonlbry)`. This will still resolve to an embed. There's not enough data at the parsed level differentiate this case -- we would need to parse the content ourself before `remark`, which I think is not worth it.
## Aside/Reminder
If you see that the link doesn't resolve to an embed regardless of the format used, that's probably just due to `5636: Disable video previews in comments/posts made by channels below a certain channel staked level`
- Channel About
- description: seems handy to have a preview, so pulled in the "allowed" logic.
- email: shouldn't render preview at all
- website: shouldn't render preview at all
- Publish Preview:
- description: there's not enough height anyway, so don't render preview.
## Issue
Closes 5193: Add filtering on notifications page
## Approach
- Add a combo box, and simply filter out the notifications based on the combo box value.
- Selection state is persistent, but reset to All if there are unread ones when entering the page.
- Tell the user that "no notifications" could be due to the filter.
