While I greatly respect the effort behind this group, I feel that the group's description is more than a bit misleading, so I would like to clarify the current landscape for anyone interested in developing mobile-friendly Drupal themes. To quote the group's description:
"We all remember jQ Touch ... Now its Sencha Touch.. a better Mobile app building framework.. As its all around jquery and html.
lets see the possibilities of having drupal themes being built using Sencha."
- jQTouch is still alive and kicking
- Sencha Touch is completely unrelated to either jQuery or jQTouch
- Sencha Touch doesn't wrap around html, it generates it.
Sencha Touch is to ExtJS what jQTouch is to jQuery.
Knowing jQuery will not help you very much in writing Ext/Sencha and vice versa.
Allow me to propose a revised group description:
"Sencha Touch is a light-weight mobile UI library built on ExtJS, with many features to offer a mobile Drupal Theme. Let's see what we can do with it!"
