I admit that now using Google+ more than Facebook.The reason that i like Google+ is due to having Google+ Bar as you are visiting Google service web site like Blogspot,Gtalk etc.With the Google+ Bar,i can perform action such as check notification, reply email quickly,unfortunately Google+ Bar will not appear as you visit other web site.
is Google chrome extension that show Google+ Bar to all website you visited automatically.Installed +Everything extension and open any web site,you will notice this;
Some of the Google service show in Google+ Bar like Google site,calender are not used always or not appear in Google+ Bar,then you can amend the source code to change the location link to suit your needed.
Visit here to download the +Everything source code .Unzipped and using windows notepad software like notepad2 open up +Everything/js/contentscript.js file.
At row 16 to 27 shows all the Google service link appear in Google+ Bar,you can delete some Google service that no need and remember to save it after amend it.
Now open up Google chrome browser to load back amended extension ,follow as picture below,
Point to previous unzipped +Everything folder and refresh browser,then a amended Google+ Bar appeared.
