I'd like to see the switchbar have the ability to group windows much like Windows XP does with similar programs running. For example, your on 3 networks, and have 5 query windows spread across the 3 networks, some dcc's etc. I'd like the switchbar to display the 3 networks your on and once clicked a popup comes up with categories (Query, DCC, Channels, etc) and inside these popup categories are a listing of the windows matching that category.
I could see where this would actually hinder navigation. But lets say someone uses mIRC on tons of networks and chats alot, this could prove useful.
With that perhaps each individual category and the windows within that category would light up much like the current highlighting.
(I did search for this and came across many switchbar feature requests, but nothing similar to this, I do apologize if I missed something)
