Create an app that opens a browser window for only one site. Much more useful than it sounds, especially as I move more of my life online. Work in web apps (Gmail, Gcal, Hiveminder, etc) don’t interfere with web browsing. More single-minded than a browser window with lots and lots of tabs. Similar to the Mozilla Prism project, but with a much cleaner, Mac-like UI. Uses WebKit to do its thing.
