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.

You can now control who can post on your public posts. This might be useful for celebrities, although I’m not really sure who it’s targeted at:

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:

Comments, feedback, discussion on this post on Google+

I was snooping around the Google+ source code, trying to get early access to the new circle sharing feature when I came across some interesting features that haven’t been discovered yet.

The first feature is pretty small and looks akin to Facebook’s wall, letting users write on each other’s profile without showing the post in the timelines of other users:

The second one is far more interesting. It looks like there’s a new product brewing inside Google named “Google Experts”. The product looks sounds like a version of Quora, letting you post questions and gather answers. Questions work like posts do today: you can mention other users, comment on them and share them.

Another interesting takeaway from this code dive: it looks like the Google+ team is working on ensuring the product works on Google Apps domains. The message that notifies you that Google Experts has been enabled has a placeholder for the domain. I imagine that this might be currently running on the google.com hosted domain.

I’ve also found the start of a new profile privacy wizard. With a bit of code wrangling, you can get it to pop up on your profile page. The Google+ team is obviously working on matching some of Facebook’s more streamlined privacy controls:

Finally, I’ve come across the wisps of Google Voice integration on your Google+ profile. I haven’t figured out what this will look like yet, but it appears to give visitors an option to call you from the webpage without revealing your phone number (like the existing Google Voice widgets):
