It's been steadily enshittifying on the user experience side too.

• subscription feed has been removed from the sidebar when expanded (but continues to exist when not)
• you can no longer add a video to multiple playlists at once. now you need to wait for the toast to clear, then press the kebab menu again, for each playlist.
• search filtering has been nerfed just today. you can't sort results by upload date anymore.

The last one basically makes my work curating new content on a search term impossible now. what a load of bs.
