I've been using this pretty heavily for the last couple of days and I am liking it with the exception of one issue which is becoming a deal-breaker for me: it defaults to opening a new tab, which means that back isn't useful. I could always close the tab, but I have that burned into my muscle memory. Since the shortcut for opening a new tab is also an easy one for most people (cmd-click) it seems unnecessary to force it, IMO. Your call, though :)
