I would like to suggest a general command to spawn in any buff by its ID, rather than just gravitation or the other specific commands. This would be INCREDIBLY useful; hope you can take the time to add it. Oh, another request - could you add a command to disable the negative buffs inflicted by developers' items, or one to just disable buffs in general? Thanks for your time.
Update: Some bugs I've noticed - the .create command appears to be bugged; I can only use it with 1-word names (e.g. Uzi or Minishark, but nothing with spaces, or it says "Something broke!"). Also, the .summon command appears to only recognize NPC ID's of NPCs from 1.1.2 or earlier, none of the new ID numbers.
