There is this super cool add-on that lets you create apps for your desktop. It is called Webrunner (from Salsita Software) It is a replacement for an app I loved dearly called Prism. I use it with a gubb.net app for my to-do list, a google calendar app, a google docs app. I even tried a gmail app but I prefer Thunderbird.
