Few things I wish they would change for creative mode.
1. Time change
2. ALL items to become infinite
3. Weather change, I don't know about you guys but rain bugs the **** out of me while trying to build.
4. Option for a flat map
5. Ability to turn off passive mob spawning. Nothing like animals jumping all over you while setting up redstone or building.
The current creative mode is pretty bad in my opinion. 2 mods do a better job then what mojang has come up with.
Single Player Commands + Too Many Items
