Review for Speed Dial by Drew
Rated 5 out of 5 stars
Everything is working great.
For those who wish they could load Speed Dial in the current tab, all you have to do is create a shortcut on your bookmark bar and click that. For some reason, you can't drag the icon from the address bar (which appears to be blank), but you can drag from the tab into the bookmark bar. Or just manually create a bookmark bar entry using the link (chrome://speeddial/content/speeddial.xul).
I suppose it would be nice if there was official support for this, because I agree, its annoying to open in a new tab. But the bookmark bar method works great, and its an easy work around.
