Twitter, Facebook, LinkedIn can be found in the majority of social media management apps. It is with Google+ that things get a little bit more complicated: very few social media tools support it due to some technical challenges.
However, most social media managers would prefer a solution that would allow them posting to all social networks in one place, Google+ including.
In this post, you’ll find reference to all tools that are to date integrated with Google+.
We’ll bring small business editions to a special focus and review social tools that (1) support Google+ and (2) the ones you can use for free or under $10 a month.

Regarding separated browser windows opened, that worked very well for me using Chrome with different user's profiles (you can also use the incognito but only allows you an additional session). If you create a different user/profile (look at the avatar on the top left corner), you can then log with many different accounts (sessions) in different Chrome tabs.
