Google "For Your Desktop App" Chrome Store App.
Google recently launched the "For Your Desktop" Category in the Chrome Store. Pocket is an excellent example. It would be cool to have something like that that could run independently of browser Windows.

I agree—this would be great. A great advantage to using this new Chrome Apps platform is that it has APIs through which you can get access to system services such as bluetooth... which leads on to next suggestion—connecting to your phone through bluetooth when you don't have internet connection, i.e. when you are on the train with your phone in your pocket and your computer on your lap.
