Right Now! is a simple pure Javascript demo of Lawnchair.js. It's probably a terrible example of how to do things, since it only ever retrieves a single key and saves it on change, but it's not expected to be more than that.
I use this as my "new tab" page on Chrame and Firefox, and it's meant to be a reminder of what really needs doing every day. Since that's the page I see most often, this is a very effective high-level to-do list that I enjoy seeing and using.
RightNow! uses the browser's localstore; all of your updates to your project list are kept in your browser, and there is no server. RightNow! is intended to be downloaded and kept on your filesystem, and you can then set it to be your "new tab" and "home page" pages, so that every time you succumb to the impulse to surf the Internet, your first view will be a list of the things you really ought to be doing.
If you just want to use RightNow!, download the ZIP file (see "Downloads" in the upper right hand corner) and copy the file "index.html" from the directory "one-page" to your filesystem, and set that page as your home page. For most modern browsers, that one page contains everything you need: embedded images, in-line styles, and included interactivity.
