Err, what? The whole point of MDI is so that you can segment information into proper windows. It's exactly the opposite of "needing to display everything in the active window". MDI allows you to NOT have to display everything in one window. This is the reason why mIRC is an MDI application. If you don't like that, then maybe mIRC is not for you.
I pointed out that it was unintuitive for those who are not used to (or don't like, for whatever reason) MDI and mIRC's interface. If you fall into this bucket, well, there's not much that can be done. Your basically arguing that MDI is an inherently poor design choice and should be removed, but MDI isn't going anywhere anytime soon, so your argument doesn't hold much weight.
