I hope focus wouldn't go to the location bar (that's what Command/Ctrl-L is for). Now, you have 2 operations thrown in the same keyboard shortcut, which doesn't comply with common standards. I'm not against providing this as an option, but the default should be to focus on the page when opening a new tab.
(Note: I'm not a usability/standards buff, so my asumption regarding standard behavior should be regarded as my personal belief; please correct me if I'm wrong. Other than this, I really like what this plugin does.)
