Thank you so much for all the suggestions!!
I should be able to get drag-n-drop working pretty easily, and swapping the layout so the buttons are on the left instead should be even easier than that. I'll have to see if I can work out a way to fit auto-naming for the image files into the program, that would be quite convenient. Though, it should probably have an option to be toggled on or off, just in case the user doesn't want to use the auto naming.
I truly had trouble finding any testers before releasing, so this really helps a lot! Thank you!
