Almost there! Rated 5 out of 5 stars
I have been u sing this for a long time, and it is extremely handy, so first, thanks Jeff for providing it...
With the recent 3.1.3 release, GDirections finally works with TBird again! Very cool, thanks Jeff!
Now there is just the one minor UI bug (see below), but other than that, gdirections now works as advertised.
UI bug: tabbing from very first 'Text' field doesn't take you to the next field, it takes you to the Location field at the bottom.
Ok, now I give it 5 stars... :)
