I haven’t found a way to do this, so I guess it’s a feature request. MP3Tag currently has an option to show the current directory — the location files were last loaded from — in the window title, but that’s not necessarily useful if you have files loaded from several different locations simultaneously, which I often do. Would it be possible to have an option to display the home directory of currently selected files, assuming all selected files were loaded from the same location, and/or maybe the common component of different paths for selected files, followed by something like
[…] to indicate that there are non-common path components?
While looking into whether what I want was already possible, I found that both my offline help, and the online help located here, are apparently not up to date, at least in regards to Options > Configuration > General, as neither describe various checkbox options available in the actual dialog, including “Show current directory in window title” and “Keep moved files in file list”. Not judging or criticizing — MP3Tag has been extremely useful to me, and I do appreciate all the effort that has gone into maintaining and improving it — but may I suggest that both online and offline help perhaps display a version number and/or date that it was last updated?
