Desktop mac OSX app: In the list of playlists in the left sidebar, it is really difficult to spot my target when scrolling. I have so many playlists, that even though I try to order them logically, it is sometimes difficult to find the one I am looking for.
Recently, the iOS app was updated to show playlist images alongside the playlist title in the list of playlists. I find this makes it much easier to find the playlist I want to listen to. Also, to have a search/filter function to filter playlists directly in the top of the list in the sidebar would be convenient.
