Hey! I like PP, it was so far worth the little money. The main reason why I use PP instead of the free available MediaCloudMac is, because PP has a customizable Playlist. I would appreciate further features like:
1- simple equalizer (to get more bass for instance)
2- right click menu on song selection. options like: "add to bottom of playlist", "song information", ...
3- better handling with songs. Instead of adding the all songs in a album if I click on a song, it would be easier if I could click on a song without doing an action. that way a user can select multiple different songs and can drag&drop them into the playlist, or could select an option via the mentioned right click menu.
That would be everything then
