I realise this is a few months old now but it's pretty clear I think:
- Desktop app (not mobile - no sane person attempts to manage playlists on the mobile app, its awful at it) - Imagine you have a sidebar with say 200 playlists. - Imagine you want to organise them - You create a folder, say.... "Work Playlists" and want to move 30 of those 200 playlists into that folder.
Current (horrible) way of doing it: - Drag each playlist one by one uuuup the sidebar, hoping the scroll bar doesnt freakout on you and shoot you past your new folder. - Drop the playlist - Find the next one in your big long list - Repeat the above.
If you use Spotify in a serious way you'll get how horribly frustrating playlist management is.
Desired Action: - Click 'Manage Playlists' somewhere - Create the new folder - Check the boxes next to each playlist you want to move - From an 'Actions' dropdown, go to "Move to..." which when you hover over shows a list of folders.
Given you guys seem to only employ 1 part time developer these days I'm going to assume much like every other suggestion on the forums that this will never happen.
