My suggetion is to have an option in the options dialog that will enable/disable the display of mIRC taskbar buttons (not system tray icon - i know this can be disabled).
My reasoning is this: i've got multiple monitors, and I leave mIRC open on one of them quite often. I can even see myself and others leaving multiple channels open. The problem is all those mIRC windows take up precious space in my taskbar, when most of the time all i want to do is monitor a channel. It would be quite helpful if there was an option for any mIRC window on the desktop, maybe just a menu item, to hide it from the taskbar.
Thanks,
