The basic demo showing off all widgets but without a back-end. Using features does not cause back-end endpoint invocations. All business flows are solely in-browser, with all that entails.
In the top-right we see the pay2myapp-status widget — allows (re)login, transaction check, logout, and payments refresh.
Just below we see an explicit "login" button (pay2myapp-appsell widget). This button always allows (re)login and never starts a feature flow.
At the bottom we see three feature buttons (pay2myapp-appsell widgets). These cause initial login and feature flows — solely in the front-end — at different payment tiers.
