Works pretty good; however, in Mac OS, I usually use Alfred and/or Spotlight search to navigate through the system.

Generally what I would expect is that if an app is already running, I can use spotlight or Alfred to take me to that running instance right away. That way I can rapidly navigate through the UI. However, with this extension, when I look for the name of my installed app and hit enter, if there's an instance running already, it doesn't care and creates a second instance, which completely breaks my navigation. Small thing, but it would be cool if it could be patched (other apps in system don't create another instance unless we explicitly tell them so, so it would be nice if this could be the case for this SSB solution as well)
