When I manage musics and tags, I use Mp3tag, foobar and Total Commander. About 10 times quicker to add a folder to Mp3tag from TC through a context menu (shell, right click menu), than in Mp3tag, using "Add folder". Unfortunately, adding a folder through shell can only replace open folders in Mp3tag, instead of adding them to the end of list.
I'd like to enjoy the "Add to the list in Mp3tag" context menu, too. Anybody else for?
