Mustapha,
Sorry for the delayed response. If you're looking to hide the Autotune button, it can be easily done in the /administrator/components/com_jfbconnect/toolbar.jfbconnect.html.php file. Around line 25, you'll see the if/else statement that either shows the button (if not in Autotune) or sets the titlebar for the area if within Autotune.
You can either comment that out for the kludgy method of hiding Aututone and then just going to the URL directly or put in the few lines of code to check if the user is the right user-level.
We're planning to add admin user-level permissions in an update later this year as well, just so you know.
Hope that helps, and good luck!
Alex
