That would be INCREDIBLE!!!! Most of those are really sweet ideas, but some of them would just give bungie a headache... In my opinion, the best ones would be:
-*****Undo option*****(I'd pay 500 MS points for this alone!!!!!!!!!)
-Drag copy & paste option
-Nameable custom powerups/multiple custom powerups
-Bottomless pit/guardian option
-90 degree snap option (except make it 45 degrees)
I don't know if I would actually buy it if bungie made this update, because I'm not such a big forge nut. However, those incredible forge artists out there could make even more amazing forge creations with these tools, and I love some of the mind-blowing maps they've created.
