i don't have much of requests but here are 2 of them:
-making the sprite editor a bit more powerful, i know photoshop and GIMP already exist but wouldn't it be better if everything the developer wants is available in a single package.
-this one could sound a bit absurd but.....a logo change?? i mean the current logo is a cog , game maker's logo is also a cog, stencyl logo is also a sort of cog. I know, when you think of game development tools you first think of hammers, cogs etc. but it will be better if we change it to something else, maybe a small competition for making the best logo??( mary jane would probably win )
