Instead of using the 'advanced search' [which btw only really works for the forums] to fiddle around trying to find what you want, a simple search bar/box for each section will do wonders for being able to find things much easier.
Ps. Is it also possible to be able to switch between the new look and old? I actually kind've preferred the old look. This one looks... too much like it's permanently in a beta version, and looks incomplete (not to mention bland).
