Persistent Fixed Tab

[MarcioSales]

My suggestion is to have an option to create a fixed tab and/or window, which can only be closed through an option in the menu. This feature is to be used in tabs that are really important to the user, avoiding having to close them in the standard procedure, which is practically an automatic gesture.
