I’ve been snooping around the Google+ code a bit and found some more upcoming features.
Hashtags are getting a bit of a boost with auto-completion. When you type the hash character, you’ll see a list of potential auto-completions (this doesn’t appear to be hooked up to any data). When you hit space, it turns into a blue block containing the hashtag, which acts like the blue blocks that contain + mentions:
Circle management looks like it might be dropping the circle visual metaphor. The new interface lists your circles on the left, although this wasn’t working very well, so it’s difficult to say what the final result will look like:
The new interface contains two menus: one replaces the existing Relevance drop-down, while the other contains some interesting new menu items. Increase and decrease circle size appear to change the size of the circles on the circle management page. Might be an internal option for the user experience team to eyeball the correct sizing:
There’s a new “more” dropdown on a profile page that doesn’t seem to do anything:
Photos are getting some tweaks. The photo previews are appearing larger in the photos tab, and there’s a new “Link to this photo” option:
There’s a new “Recommendations” link on the left side of your home screen that links to a page that doesn’t exist yet. Clicking on the Recommendations link takes you to a 404 page at http://plus.google.com/plusones/posts.

Individual posts are now getting a “Hangout” button. Discuss a post in real-time with others that have seen it!
You can now mute a person, in addition to a single post:
Games may appear in the right sidebar:
The post sharing dropdown is getting a bit of a makeover with item icons:
I’m not sure if this welcome page was already there, but I haven’t seen this screen before:
