Hi,
MM playlists store Track IDs from library and that is why additional steps are needed.

Anyway I added https://www.ventismedia.com/mantis/view.php?id=15354 so that we can investigate how to improve that in future

Windows folder file list, it works fine when I D&D into now playing, but then I have to select those selections right click and add to selected playlist. I just want to do that same but add them directly to the playlist when I select it. There is no function for that?

Where are you using D&D from?

Drag and drop to the current playlist is not a function, you can do this in now playing then add those to the current playlist which is kinda tedious. Also right click on the current playlist listing there is no function to add music files to it. Some of those changes I'd like to see.

Thanks! Cyg
