First, there is no way that I can see to create a new alias/trigger/script group. It'd be nice to be able to have my scripts self-organize.
permGroup(name, type)
Second, there is no way to have a script create another script, which would be -very- useful for creating events on the fly. As it stands, if you need to tie something to an event, you must use a script... and you can only manually create scripts.
tempEvent(event, luaCode)
or even
tempEvent(event list, lua code)
