I would like even not having a tracker, and for photos/videos just when you go to a folder, thumbs not already done are generated and saved for next time.

For music I would like to have folder loading (including recursive loading), current playlist management (adding and removing songs or folders), stop when disconnecting headphones, and continue when reconnecting them, autoplay when opening app in the song and time where it was when you last closed it. personally I don't care about saving/loading playlists, tracking or even tags and media art. Having it could be great, while I can manage my music by folders.

I am not rich but I would donate something for that features. If they are implemented in the original media player, it would be fantabulous!
