When loading a GUIObj into the game, the position stored in each GUI element is always relative to the center of the screen (i.e. 0, 0). It would be nice if you could choose, while in the GUI editor, where each GUI element is relative to. I.e. instead of the center maybe you want it to be relative to the left side, right side, top , top left, top right etc. etc.

Then when you load the GUI objects their Rectangles are set relative to where you chose the GUI object to be relative to rather than always in the center.

This would greatly improve the Gui system as a whole. In my case I had to do my in game HUD all by code (i.e. no gui editor) because it was just easier than using the current Gui system.
