Angband and its variants have multi-window support.
And it's godly. Holy hell is it glorious. You can customize the font size on each individual window, you can resize them, you can pick which ones you want there, you can go completely without them. They're an optional feature that makes life easier for people who know it's there prefer them.
I think Cogmind would benefit by having something similar available. It'd allow for more(or less) space to be taken up by the map depending on your tastes. It'd allow multi-monitor setups to feel like massive robot access terminals. Most of all, it'd allow my ally and calc windows up simultaneously.
I have no idea if it's even remotely feasible without a massive rewrite, and I doubt it'd be doable within any sort of shortish timeframe. Like the thread title says, this is entirely wishful thinking.
