Goto Anything can focus on already open file instead of opening it again.

I'm a huge user of the two group layout and really wish this behavior (only open a file once among all groups) was the default or at least configurable. When you have multiple groups with 10+ tabs each I'm constantly accidentalliy re-opening the same file in a different group because searching for an existing tab (that I don't remember is already open or not) is too slow.

I understand that you need to allow people to somehow still open the same file in a different group, but that could instead be done by a right -context menu or some kind of "split" command.

There's actually a command New view into file for opening the same file in new tab, so I really think there's no reason not to add a configuration option to re-focus existing tab in any group/window. That would also allow us to use Goto Anything for super quick tab switching without ever reaching for the mouse.
