Add To Playlist: sort by last recently used

[tfga]

Describe the feature you want

When you long-press an item and select "Add To Playlist", the playlist list that appears then should be sorted by "last recently used" (LRU).

Is your feature request related to a problem? Please describe it

If you're adding multiple videos to the same list, you have to select the same list over and over. If the list happens to be the last one, for instance (and you have more than 20 lists), you have to scroll down to the bottom every time.

If this list was sorted by LRU, the experience would be better. From the 2nd time onwards, the target playlist would be at the top. No need to search. No need to scroll.

And, IMHO, when you're adding a video to a playlist, the likelihood that you want it to be added to the same list you used last time is high enough to justify this behaviour.
