Please bring back the trees and drag-and-drop options, especially for the playlists. I have a lot of music and several hundreds of playlists. Unfortunately, I cannot properly use them in the newest versions of Helium (12 or 13). Browsing several folders is a pain, I cannot fill the playlists from the Music Explorer via drag-and-drop and I cannot drag-and-drop playlists in other folders.
I am a long time Helium user, my first version was 10 but I also bought the updates until version 13. Unfortunately, I find myself using only version 11, since a media player without proper implementation of playlist is useless to me. All of the above was bautifully implemented in version 11. Please, bring those features back.
We have started to review if playlist support can be implemented.
When that's implemented we will review drag and drop support (which should be partially there already for other node types)
