I've been programming since 1976.

The buttons are still in every section, allowing you to unwittingly erase all your settings and lists, in one click, without even an "Are you sure you want to set all preferences to the default settings?" prompt.- that's a HUGE, HUGE, HUGE bug.

I have (had) over 400 blocked hosts, and approximately 180 keywords in my list.
Doing them one-by-one?... OUCH!...
