Hey just some ideas, if they already exist please tell <img src="smileys/smiley12.gif" border="0" align="middle" />
Being a newbie i rely quite a bit on overlapping to trigger events.
I was thinking of using empty sprites to do this, because i have heard that they (or invisible sprites in general) don't slow down the framerate.
So wouldn't it be convenient to have a button to change the color of a empty sprite? Perhaps 10 colors yes?
Also
A button to display the the collision polygon inside the layout
(not only in the image editor)
cheers
