I've recently switched from IE to MyIE2 and I absolutely love it because it's basically a tabbed browsing interface for IE. I use it so much though that I am used to using my middle mouse button (scroll wheel) to close tabs. I end up trying to do the same thing in mIRC because it has a similar interface (title bar/menu/toolbar/windows) and every time I do I kick myself. It seems like there's not an easy way to close one (or especially many) windows. There's Ctrl + F4 if you have a rather large hand-span; the window's small X button, but that requires an awful lot of mouse movement back and forth and aiming on the small x instead of the larger mIRC X can be tricky; right clicking on the window button on the taskbar is almost as bad, that context menu is GIANT and close is all the way at the bottom. I'm sure it wouldn't be much work to implement but I'd like to hear your thoughts as well.
