    Default How is the tab bar implemented?

    Just wondering how the tabs work, as in theory they should be impossible. As far as I know mobile browsers tend to not support position:fixed and similar "tricks".

    Does Sencha Touch implement custom scrolling? It looks fairly good, but when comparing it to a "normal" web site I had the impression that normal web site scrolls a little bit smoother (tested with Android on a Nexus One).

    It might still be a compromise I am willing to live with (since there are also no real alternatives), but it would be nice to know how it works.

    The problem with mobile OSes is they don't scroll very well in divs. Lots of times you have to use two fingers (iOS5 helps a bit I believe) so yes, Sencha Touch has it's own scrolling to cope.
