Just a random wish..
I need some kind of test room I could enter without a character so I could remember all the syntax + get prompts figured out. :(

change locdescs would probably work for that, if you really can't figure it out without looking/feeling like a total idiot in-game.
It was as much the need for instant gratification without a character as shame.
I used to want (and sometimes still do) a room where I can test out
(a) what other people see with hemote/semote/emote (because I forget)
(b) the various syntax things with emote (because it's complicated)
So a room that would be like a mirror, where you type something and you get an echo back which is what other people would see.
