Cool, thanks for releasing it. I'll try to play around with it when I get a chance. As for the column sizes too small or large I agree it's an issue, same with weired floating behaviors. My current solution is to set min widths, so that it doesn't get crazy once the browser is smaller than the standard screen size (960px).
Fortes The advantage is that even percentage-based layouts won't look great at all sizes (columns can end up too big or too small as you get to very large or small screens). Floating divs can work OK in some situations, but not always.
It really depends on the situation though, not all pages would get much use out of the script, but for some projects, it's been really useful for me, so I decided to release in case others wanted to use it as well.
