One thing I do miss is the "Last 24 hours", "Last 7 days" etc quick-links. I have found the Active Topics for the last 24 hours, which is nice, but I can't do the others. The search engine lets me specify 2 or 7 days but won't let me search with blank search terms.

Just in case you missed it, the last 24, 48 and 7 days are now at the bottom of the front page.

The SQL error, seems to be a temporary thing. All SQL errors after you posted that one have been logged, and will be looked at to see if it can be fixed.
