plg jopensim quickicon
This plugin provides a quick link in the toolbar of your administration control panel
By default it appears on the group EXTENSIONS
If you want to have this icon up on top, you can do so by duplicating the admin quick icon module, give it the group name mod_quickicon2 and sort it up.
The icon still will appear in the original module under EXTENSIONS though unless you hack Joomla core files (I hope I'll find a solution for this in a future version).
