SUGGESTION: Open Favorite directory if last used directory doesn't exist

I often use a temporary area to modify my files before I move them to their new home. The next time, I open MP3Tag, it tries to open the last folder used (totally fine), but if that folder doesn't exist anymore, it instead opens the application folder.

I know that there is already the "start from this directory" option, I would like to request making it just a little smarter so that I could open the last one used if I had to stop in the middle of a project.

Thanks for the suggestion. Sounds like a good idea to me!
