When opening a project: Switch to already opened window?

[jordan-brough]

On MacOS in Sublime Text 2 when I:

• Already have a foo.sublime-project open

And I:

• Double-click the foo.sublime-project file in the Finder
  OR
• Execute subl --project foo.sublime-project in the Terminal

Then:

• Sublime comes to the foreground and switches to my already open project.

However Sublime Text 3 instead opens a second window with the same project.

Is there a way to get the old behavior back? It’s very handy especially when combined with tools like Launchbar.

Thanks.
