[Wishlist] Option to display the Alternative menu notification or not

This notification is displayed for any entry in the Alternative menu. Normally, it is cleared by Windows automatically after a 10-30 seconds. QAP has no control on this duration.
 
The goal is to explain new users what to do after they selected a command in the Alternative menu. What I could do is add an option to make this notification optional. It would be true by default and experienced users could turn it off.
 

Done in v9.1.1.
