I think this is what was meant first off (and would make this better) is the use of toggling each section on and off. Personally I never use quicktexts or sounds so i could turn them off and not worry about them when im trying to look through them all, but i can easily turn them back on if i decide i want to send /sevillaugh (or whatever it is, I use it once per month if i feel up to it
).
This way you can refine the intellisense, but still have full functionality quite easily.
I understand the statement about /away and such, but I don't think that is TOO much of a problem, people should notice if the Plus! commands aren't there I would think.... (but then again maybe some people might miss it I do understand).
