Design Team/Activity Touch Input

Turtle Art

Canvas zooming in/out with pinch gesture
Canvas scrolling when dragging canvas
Default to large blocks when used on a touch device (reduce obscuring effect of fingers & improve hit target)
Portrait orientation clips too many toolbar icons (expect portrait orientation to be used much more frequently on tablet devices)
Toolbar hover hints clobbering view of block palettes (due to touch activation leaving pointer over toolbar buttons )
Allow escaping from full screen mode (see Read for improved behaviour)
