Best not to cross-post!
I think your idea is a good one, could be useful for people. I don't personally need that kind of feature, so I don't know if it's simply been moved or edited in 6.12 rather than completely removed. I agree that, if it has been removed, it might be nice to see it again.
Just a note, mIRC versions are never "fixed" - if Khaled chooses to add it back then you'll have to wait until the next version. Also realise that Khaled does not reveal what is and what is not going to appear in the next version's of mIRC, so it's a matter of "wait and see"
