It's not impossible, but it is usually the sort of thing done using the operating system's theme settings.
No, it makes sense, especially with MUSHclient as it is. I think on more modern OS that philosophy has changed - or, it seems to - I know nothing at all about official standards, but I know on Windows 10 now, if I open Chrome, all the titlebars and frames are black/dark... in Thunderbird, they are a light blue... Sublime text is grey... windows explorer is white... Steam is a very dark grey... Photoshop is a light grey...
It seems that there's been some recent trend for programs to all have their own colour themes rather than JUST use the Windows "system theme" BUT I suspect this might be down to how Windows 10 handles these things backend, and would NOT play nice with all the (I know there are MANY) users that have older Windows - and the quite a lot that use Wine to run MUSHclient on Macs and Linux, so I imagine things might get "messy".
It was more a passing thought, one of those "It'd be nice if..." but only if it were a simple world!
