while i was making some things for fun i noticed that you cant select some tiles and move it with the arrow keys alone, you must hold shift, and unless you go and change your document grid size to the tileset size it moves incorrect which is a massive pain in the ass
and the quick grid settings have a visual bug were the number that is show isnt exacly the size that it currently is
i wanna point out that moving with the mouse works just fine, its just the arrow keys, which is annoying cause that generally the main method people use once they are accustomed with the program
