Hello - I love this software, its great, I've been using it for a few years now...
One feature that would help, is having a input box in the change directory window, to allow directory paths to be pasted in.
I usually have the folder with songs already open in windows explorer, then switch to mp3 tag to read in those files. So pasting the directory path in the change directory window would be nice.
I suppose right clicking on the folder from windows explorer and chosing mp3tag essentially does the same thing.
