Thank you very much!
I don't usually edit my games very much after releasing them, but may consider adding some of these changes sometime just because it's so popular, especially some of those assets.
The color wheel / presets are built into the game engine so I'm not actually sure how to fix that glitch other than removing preset colors entirely (maybe that'd be fine because there's an eyedropper anyway?), but I should be able to do the rest in some form or another. While having a photoshop layer list would be tough, I should be able to at least display the layer of the object last selected, for example.
