Am I correct that WinCustomize determines its width by the screen resolution?
If so, a better way to do it would be browser width. The problem is that I am at 1280x1024 but have a couple sidebars that make my browser area about 900px wide. WC keep delivering me pages that can only be viewed fullscreen for me, and if it is normal mode I have to scroll horizontally quite a bit.
I think this would be a simple fix.
