Google is moving swiftly with its brand new social network that launched last week, and is pushing a large list of changes and improvements over the next week as an ongoing effort to improve the product. The speed at which this release has been announced is impressive, and the list is not disappointing by any means.

Geek.com reports that the following list was extracted from comments on Vic Gundotra's Google+ page, senior vice president of social at Google;

Ability to modify circles a post is shared with after posting it

Reading sparks and +1 comments in the Android app

Lifting of the 5000 circle cap (really?)

The ability to overlap circles

Option of a circle that doesn’t show up in your stream

Menu follows you down the stream as you scroll

Easy private messaging option including to person who starts a thread

Google+ app for other platforms (WP7)

Blocking working 100% of the time

Easy way to merge circles

Sharing and refresh updates in the Android app

Link to hide all comments again after you’ve clicked to show all

Better integration of Google Chat with Google+

Fix issues with instant upload for photos

Ability to share with all circles, but with an “except” option

Ability to share Google Docs and Calendar with circles

Revamp Google Reader to make sharing easier

File-sharing integration

Nested comments

Addition of hashtags to aid searching

Most interestingly, the new release that's being pushed in the next week means that Google+ will have an application on Android, iOS and Windows Phone 7 in the near future, which covers off the main three phone operating systems. There's more on top of this list, but the company is yet to formally make the announcement.

On top of this, Neowin has found a form created by Google that has become available for businesses to submit their details for Google+ "Brand Testing," which will be similar to "Pages" for business on Facebook. We're told that the form must be filled out by 6PM, Friday 15th July PST to be eligible. The form can be found here, and it asks questions such as "what other social presence do you have" and "what would you use your page for?"
