Playlist Revision History Feature (Kind of like Google Docs)
Primarily web, but really both web and mobile***
I've almost saved over the wrong playlist a few times when building playlists on the web, and have accidentally modified and lost songs on mobile playlists when both building and using.
So I'd like to suggest a 'revision history' or 'previous versions' function for playlists. As I've also suggested a playlist 'lock' previously, I think somewhere in the UI for playlists ther could be a dropdown giving the ability to choose between 'listen' mode (listen to playlist, but no editing), 'Edit' Mode, and 'History' mode (which would allow the user to change the playlist to previously saved versions of that playlist, but still be able to switch back or to others... maybe 3 to 5 per playlist?).
Also to automate it, if Astiga could periodically check for changes in playlists (perhaps every 24 hours, every month, every X times the playlist is opened or something like that) and provide a little indicator/icons to show if (since the previous version) songs have been added, deleted, and/ or reordered (relative to songs that were present in the pervious version) it could run extremely smoothly. I hope this may be a useful idea. Thanks for always improving Astiga!
