I use a 22" widescreen monitor at the same resolution. Granted, I also have two chat windows (each with at least three tabs) and 8 hotbar banks open, so that takes up a fair amount of screen real estate.
Even with so much space to play with, for the vast majority of windows, I see the titlebar as entirely superfluous and a waste of code and space...you can usually tell what a window's for by its contents. I personally don't need something telling me I'm looking at the "Knowledge" window if I'm the one who pressed "K" and I'm now staring at my list of known spells.
Thank you very much for the compliments...they are greatly appreciated, and I'm tickled that someone else enjoys these mods as much as I do.
