Regarding the regex support in events, it supports all features $regex() does. The problem is with special characters like "{" , "}" and ":". Since ":" is used as a delimiter in the event header, you can't use the (?:) item because the parser doesn't know that the ":" char is actually a part of the regex. Similarly, \d{1,2} can't work. Negative/positive lookaheads/lookbehinds (and anything else that doesn't contain these special characters) work fine.
I'd like to see a method of getting around these issues, although I imagine it won't be that simple.
Regarding the mirc Editor showing only 24 items and More..., I totally agree, it has to go.
