Hi, can you add feature ? Creating "relative" playlist in folder and ability to create filename with variables ?

clarified in one of the comments with

ad2, When click SAVE button, then rename mp3s id tag and create file
(for example)
G:\IDM\Labels\Muteme\Neutrino-Cosmix_Songs_(Muteme,2006)\mtme003-Neutrino-01-Twin.mp3

When is it finished, iit would be great to create playlist like this with m3u,pls or toher extension

mtme003-Neutrino-01-Twin.mp3
mtme003-Neutrino-02-Time_Defrost.mp3

mtme003-Neutrino-08-Unnamable.mp3
mtme003-Neutrino-09-Flowave.mp3
mtme003-Neutrino-10-Break_Doors_Theme.mp3

ad1, i think create filename of playlist like filename of mp3 ( %artist - %albumm.m3u )

This seems like it would be better as a plugin, but we don't really have anywhere to request plugins, so...
