Hi again , I have already done my last request (make a call , wait 4:30minutes and if call is till active hang up and dial again).

I dont want to be off topic but now this is my question.

Is there a wey to get this done?
1.- Remove the WEB icon (launch microB browser) from the menu.
2.- Use the "Desktop Command Execution Widget" or a desktop shortcut to a little app.(.sh or .py) that ask for a password before Launching the Browser.

If there's no master password for the browser maybe we can prevent simple users to use It.

this may also be useful for other apps like Email client.
