You are not the first one...
One of the bigger efforts lately: My redesign continues by kimmel.
Most people seem to be satisfied with the predefined layouts or their own CSS tweaks. See Display Settings.
Here's a screenshot using
my personal CSS - setup. Maybe, you'll don't like that either, but it demonstrates that the current
HTML layout already allows to tweak a lot.
However, I fully understand what you mean. When I came here first in 2007, I thought that this site was abandoned long ago - maybe since the late 90ies? Then I
scrolled down the alley of tables expecting to find an Optimised for Netscape! - but instead I found an excellent node by some ikegami guy, posted some minutes ago. Hooked.
