I'm also giving attention to the layout and especially element spacing; trying to generally improve the intangible "feel" of the site through subtle tweaks that make things much more visually pleasing.
The goal here is to clean out as much legacy cruft as possible, so I can more easily make more complex (but necessary) UI changes. There are still too many tables used for layout/formatting; I'll be trying to eliminate those next.
I'm back to working on this thing for my sake, solving my own needs, making it into something I want to keep on using, and I must say it's a nice change. Yay for (useful) productivity!
