This is of course a great boon to owners of landscape phones such as the Droid, Epic 4G, or T-mobile G2, but it is also useful for portrait phone owners as it offers you a secondary space to place widgets that you might only want to check every once in a while, like news headlines or schedules. Of course, you could always put them on your homescreen, but we know there are a lot of minimalists out there who would flinch at the thought of a calendar widget besmirching their beautiful/OCD arrangement.
QuickDesk Pro is a worthy update to one of Android's truly unique and useful applications. If you haven't already, be sure to give the standard QuickDesk a shot. If you like it as much as we do, the ~ $1.99 / €1.50 price tag is a no-brainer for the added functionality the Pro version brings.
PS: @ruqqq has been hinting that he has a launcher in development as well. Considering HelixLauncher was undoubtedly the smoothest launcher for Éclair, we'll be definitely keeping an eye on that project's progression too.
