It would be very helpful to have an option that, when set, would automatically select all files when mp3tag is launched.
hit Ctrl+A ...
Sure, that works, but it would still be handy to have all the tracks automatically selected. I almost always use Mp3tag on an entire directory containing a single album. The individual track tags will already be there from the ripping process and I just need to run one or two actions on all files in the directory.
Sorry, but this was already requested before.
I don't plan to add an option for it ... it's too easy to press [Ctrl+A]

Here's the drill; it's the same exact thing every time I rip an album: I right-click a directory, select "Mp3tag", then when in the program, type in [Ctrl+A] on the keyboard, then go back to the mouse to select "Actions", click on an action or two, click "Ok", click the "x" to close Mp3tag.
How about a "Select All" button that is so common in many programs?
