The revised downloads section is now online. Some of the elements (i.e. the option groupings) only appear in newer browsers, but that doesn't make it any less functional for older browser users - just less pretty!
I decided to ditch the cookies support though - its needless fluff and would tie up server resources. The V4 Biorust design will be quicker-loading anyway, reducing the lag when filtering the options.
PS. Yeah, the filesizes don't order properly... i'll fix that too =]
Update: Filesizes fixed now too! I should have the tutorials following suit with a nice list-box filter system shortly...
