Congratulations on the update! The tool is so good it's scary! The only reason I still don't use it is the fact that, when exporting the frames, the "_" is placed between the tag names and between the numbers to separate them. As I still edit a lot of my game images and they are saved with "-", I unfortunately can't save over them. It's a lot of work to save in another folder, edit the names and cut to the original folder.
Do you intend to modify this one day so that it is possible to separate the tags and numbers with another character (or maybe not separate)?
