I noticed that I cannot 'not add' subfolders to my library without 'not adding' the main folder too, when there's only one subfolder. Let me explain with a picture:
I can uncheck the subfolders COPERTINE and FREEME2 (keeping DOWNLOVERS and MUSICA) without necessarily unchecking the main folder LA MIA MUSSICA (or at least I guess the full blue square means I'm still adding the main folder to the library). But when I try to uncheck RAPPELZ MUSIC, the program automatically unchecks it's main folder MP3 too.
Now, in this case LA MIA MUSSSICA doesn't contain music files, so I'm not sure if MM adds it or not to the library, but RAPPELZ MUSIC contains several mp3s which I don't want to add to my library, while I want to add the files contained in the folder MP3.
So, is there a way to add the files in a folder without adding it's subfolders too? Is this some kind of bug?
