The default desktop app for Hangouts doesn't float your boat? https://support.google.com/hangouts/answer/6098392?hl=nl

Not really. It had an ugly bug for osx so I didn't use it that much.

I got sort of used to the chrome extension, but that uses to much screen space. I want an app that takes advantage of the notification system built into OSX.

These sort of wrappers (like op's app) get really close to native apps (in terms of ui/ux).
