Uncircle+ is a google chrome extension that lets you easily uncircle (that is, remove) inactive people from your Google+ circles so that you can add more people to your circles later without reaching the 5000 limit.

Inactive people are those people in your circles who have not shared any posts (original, reshare, private or public posts) with you. Having at least 1 such post is a sign of activity.

Uncircle+ behind the scene:
Step 1: it collects a listing of people you’ve added to your circles.
Step 2: it checks the activity of these people.
Step 3: it shows you inactive people and lets you select which ones to remove.
Step 4: it removes selected inactive people.

Why do you need it?
Google+ lets you add a maximum of 5000 people to your circles. Nevertheless, not all of the people in your circles are active; They just count towards your quota.

The PlusClout score is based on numerous public variables like number of followers, frequency and volume of information sharing etc. Mix in some mathematics and you have a PlusClout score.The PlusClout score is a number between 0 and 100.

PlusClout is kinda like CircleCount we talked before,the different is that CircleCount count your Google+ rank and PlusClout count your Google+ Score,i prefer CircleCount somehow cause rank data more valuable to me,but you can still give PlusClout a try to have more accurate data about your influence on Google+.

PlusClout.com also supply a PlusClout Profile Widget which you can embed on your blogs or websites.

To use the extension, follow the link below and install it. Go to a page listing the profiles you would like to add to Google+ (sites like group.as and recommendedusers.com are great for this). Click on the circle in your title bar and choose the circle name you would like to add them to. Watch as the profiles are listed that have been successfully added.

Please keep in mind that limited testing has been done with this extension and there are plenty of signs that Google+ have limiters on how many people can be added within a given timeframe. Do not abuse this extension.

Google+ is social networking done right. Available now, we bring you a homescreen experience to mirror the one you are getting with the Plus website and application. Google Plus and Tha Plus are perfect together!
*When you use this theme, you get a graphically enhanced action bar that works in both portrait and landscape. Did I mention that we also include wallpapers? We do!

*But we are not done yet! You also get a icon set that automatically themes your system icons! They are built into the theme for use on homescreen, dock and ALL icons can be used for custom shortcuts by accessing the iconpack.

If you like how the icons look and want to extend it to your market icons, take a look at the pro version of this theme! Search for ‘tha plus’ or click the link on the left to view my other applications. You’ll find that and more!

*Regarding ‘MovetoSD’ availability: If the app is moved to SD Card, you risk the custom icons not loading properly because of how the system loads the SD card.
