I like that the center column's size is variable, but there's a point where the variability allows the content window to shrivel away to a mere sliver of itself.
I regularly split my screen vertically when surfing the net, editing page to code, etc., a window on each side. When I do that the variable nature of the center column creates a page where the post / page content is so narrow you can't really view it comfortably. So, I wanted to see how I could limit that variability, cap it once it reaches X pixels, or X% of the whole. To me, the content is the most important part of the screen, so if it gets too closed in, to the advantage of the right and left sidebars, it defeats the purpose.
Suggestions? And thanks.
