I generally like the theme for its overall look and feel (from the preview at least). I agree the sidebar font colors should be a bit darker for easier reading.

I'm not a fan of the footer scripting, for a number of reasons, my biggest concern would be if they were having issues with their site would it create issues with mine?!

Removing the footer script would be against the license terms, and therefore make the theme virtually unusable for myself ... it's also the reason I did not use another theme of theirs that I really liked.
