Simple ToDo-List Javascript application for the smartphone

I wrote a simple ToDo-List application in Javascript to use it in the smartphone. To try it, you need to download the todo-list.html file and then open it with your web browser (Note: not every smartphone lets you open correctly the downloaded HTML files):

It is just a HTML document that "saves" the items as parameters in the web browser address. This approach gives me persistence, Undo and Redo operations for free, just having it opened in a tab of the web browser (Note: it will work only if your web browser is configured to remember your opened tabs). Enjoy it!
