The display info at the bottom, that lists number of files, size, time etc.. gets overruled when a song is playing and trying to be tagged.
The message 'Saving tag changes..' is fine. but it would be nice if MC instead of briefly flashing the normal data (when changing a view, updating a list, clicking on a new song etc..), showed it for just a bit longer and faded back to the 'Saving tag changes', after a second or 2.
