I have no clue if a similar idea was posted.

Instead of bothering to cram the topic into the mIRC titlebar there should be a bar that goes at the top of the channel window that shows the channel's topic. I always find myself scrolling up or typing '//topic #' to gets links and news. This feature is best expressed in Conference Room's 1.x java client.

Another idea is to make the nicklist (and probably the channel bar) easily collapsable if you need more room to see text.

One last thing... is there any chance of adding italic support to mIRC? They have bold... why not italic?
