All Google+ extensions and apps below require the Google Chrome browser. You can find me on Google+ here.
- Replies and More – Adds a drop down next to share with additional sharing options like Twitter, Facebook and Email. The extension also allows you to easily reply to the author and mention other users in your comments. Also try Extended Share.
- Comment Toggle – Hides any comments to posts within your stream and makes them available when you actually want to see them.
- Move 2 Picasa – Exports all most of your Facebook albums/photos to Picasa. I’ve had hit and miss success with this app, so just be aware of that going in. Start Google Plus is an alternative that I’ve used, but takes a little time to move a large amount of photos over.
- Start G+ - Automatically post to Facebook and Twitter when you share something on Google+. Additionally, it puts your Facebook and Twitter streams inside your Google+ feed. The only downside is that you cannot reply to or like a Facebook or Twitter post within Google+. This extension is far from perfect, but it will do until Google adds these features.
