Something inspired by the impossible design I wrote about in 1.9:
Add 20 theme to the Moodle 2.0 core
Went with "Fusion."
Slick! I love it!
One bug is that the blocks column uses a percentage with no minimum, so it shrinks down weirdly when you make the window smaller.
I tried fiddling a bit with adding min-width:200px to various block divs without success (everything fell apart). Hope this is something easy for you!
I originally tried this without much success. There has to be something I can set that will stick. Let me give it another go.
Added min-width on #wrapper to resolve issue.
Fixed via updated page width.
