DitherMaster will get a new fully overhauled version called “Studio” on Steam. I think a lot of the UI/UX problems you mentioned will be fixed with that version!
If you are interested I can give you a beta key so you can play around! Either hit me up on the Discord or drop me a email: info@gravehammer.com
