I'll add:
Make the location bar a little more "awesome", if you will.
Eg, about 20 times a day (once if my boss asks anyone) I do: cmd-l, sla and I have to down-arrow through pages of whatever slashdot.org urls are in history, to get to
http://slashdot.org/. I have *never* *once* typed in, 'cmd-l it.slashdot.org/blah/blah/blah'. It would be 'awesome' if OW knew, "homeboy only looks at the home page, and doesn't care about every url we've visited in the past".
