Reopen all BTT windows after restarting the app

@Andreas_Hegenberg Unfortunately, after restarting BTT, the previously opened configuration windows are not restored.

Because it is very practical, I often work with several configuration windows that show different things. After restarting BTT, I have to reopen these windows manually. Would it be possible for BTT to do this?

Ideally, minimized windows would also be reopened minimized. But it would be enough for me if they were opened at all. Thanks!
