There is only one page. It has two components: authentication and the scratchpad. This is mobile only, there is no desktop version. # Authentication The authentication component has several states: * not logged in * logging in * forgot password * registering * [fb login] - empty * logged in When not logged in, the component shows three buttons: [Come in with Facebook], [Login with Email], [Register with Email]. When logging in, the component has inputs: [email], [password]. link [Forgot?], button [Login] When forgot password, the component has input: [email] and button: [Recover Password] When registering, the component has inputs: [email], [password], [re-enter password] and button: [Register] when [fb login], the app delegates control to facebook, so there is no UI for this state, nothing to be done here. when logged in, the component displays the email, and has button [Logout] # Scratchpad The scratchpad component has two elements: a textarea and a button [Save] The button blinks (transitions states ACTIVE -> INACTIVE -> ACTIVE) upon clicking.
