The image editor is different. I didn't want something that was the same as everything else, I wanted something that I knew worked well for pixel art, and this does. Yes, it's different, but it's also incredibly powerful once you're used to it. The whole editor is "brush based" and that's not going to change....
I'm also not sure what you mean by "messes up the colour" on rotate....?
Good!
I have a few gripes with the image editor, but its much closer to ProMotion than Photoshop. That is a Good Thing.
If anything, it needs strong UI/UX improvements. Its too nested in the basic IDE to function correctly, things are hidden in the menu way up top and hard to get to, the UI is 'too pretty' and isnt clear or intuitive. It seems to have lost a ton of functionality.
Im just getting into the image editor, but please add 'revise and iterate a better image editor' to you roadmap and really spend some time on it.
Personally, I do not like that RMB is a color and not a menu, that is a jarring and nasty shift from almost every other image editor, but I get
why you did it.
I will be making a list of things with the image editor that could use some polish, but its not a bad setup. The theory behind what you are going for is good, its really good for what game maker is and does. I love some of the new features, but it does need a lot of work.
I dont think it will be 'yoyo soon', but make version 2.2
or something, all about the image editor. As in, 'the image editor improvements version'
