Dimensions can already be changed (Animation --> Resize Frame). Hotspot, coldspot and gunspot have been implemented, but is disabled due to ethical reasons. Why ethical? Because in an experiment I performed, I set the gunspot REALLY FAR away from the actual position, and killed someone in a multiplayer game without being near. In other words, this can be used as a cheating tool

Having been here during the "good ol' hacking days" where programs such as MegaWarp caused a lot of cheating, I was thinking it would be safer not to enable these features (yet). On the other hand, most people here are mature and don't cheat anyway. Either way I'll probably have to wait for some reassuring comments first.
