Staying on the subject of what sencha does and does not.could anyone pls tell me if Sencha touch supports the use of canvas
Sencha is develope to takes the best of HTML5 standards so yes it supports canvas.
Anyway, I made some test using canvas animations on mobile device and the result is not really great for these reasons:
The animations running very slow.
My iPad ran out of battery very quickly.
So if you have to create an animation I really suggest you to use CSS with Sencha Animator.
For other little things where you don't have to call a rendering loop, the canvas works great.
Hope this helps.

iPhone has the main app screen which has apps and a background which you can slide form side to side to see a new group of apps. Is it possible to duplicate this set up?
I played around for a few hours with this problem. I am pretty sure that with a bit of time and well thought out approuch that this wont be a problem to do using Sencha Touch.
