Easier add/remove from playlist ui + playlist suggestions

id love to be able to click on a playlist and have recommended tracks for the playlist at the bottom or something based on the music thats already in there. id love for the ui of that have an easy “+” button to auto add it to the playlist.

id also love to see an easy remove from playlist button when specifically playing from a playlist, as i tend to make big playlists, then listen through on shuffle to see if anything is too jarring and needs to be removed; especially on my sleep related playlist;

always clicking the 3 dots is a bit cumbersome for adding/removing songs to any playlist

id also love a ui change where i can drag and drop songs into a playlist, but thats me being really optimistic.

Swipe to the left.

What about for the desktop app??
theres no way to remove from playlist from the now playing screen, and my playlist is so big its hard to scroll through and find the currently playing song that i wish to remove
