@$bill, In response as to why I am not using the launch feature of the app, it's because often I get to a specific web site page by clicking on a link in an email (ones I trust, of course) or navigating from other sites. This will often redirect me to the login page and then take me back to the desired content.
Of course, I suppose when that happens I could go back to the link, launch the Lasspass app and sign in to the desired site, then switch back by to my link and click on it again and it should be already signed in. Is this what you mean? Is this the best way?
I suppose it could work a similar way in Windows 8? But not as convenient as a built-in browser feature.
