@Hawkee - On some pages (such as in a snippet), the links in the footer are unclickable. Adding position:relative; to the #footer declaration should fix the issue since the z-index property doesn't work on statically positioned elements.

For some reason, even though the header remains on screen at all times, I still scroll to the top to use it. I feel like I'm not doing it properly. =P

Hawkee, quick suggestion. Could you add a button to expand or collapse the main header? It can be a bit distracting when trying to read something on the site.
