We do agree that this is a great idea! We will certainly be reviewing the feasibility and considering this enhancement.
We did want to comment that once an end-user is logged in, they do not have to login again if they switch a page. Their login credentials should be retained by the session (browser) and not require any additional login for any page(s) they have permissions for. Once they log out - or should they move to a new browser, yes, they would have to login again.
