Design Team/Sugar Shell Touch Input

System wide

Hide pointer cursor when touch screen interaction is occurring, reveal if/when mouse or trackpad is used
Palette hover/click behaviours
- Single touch should _not_ trigger hover delay palette content (to prevent toolbar palettes and help hints obscuring UI after use)
- Touch and hold should trigger hover delayed palette content (like a right click)
Hide all keyboard shortcut accelerators when booting on touch only devices
Make toolbar overflow drop-down widget a standard sugar toolbutton width to allow easier access
Up/down menu overflow UI too thin (hard to scroll up, gtk combo widget needs work here)

Touch and hold on an activity icon should open the full palette (like a right click)
Touch dragging on an activity icon should allow that entry to be dragged to the bottom Journal pane UI for copying to another location
Touch dragging up/down on the canvas should smooth scroll the Journal list
Touching the Sort view toolbar icon while the palette is already visible, should dismiss the palette (should use this behaviour system wide)
Single touching a combo widget (e.g. Anything, Anytime) should lock open the menu for easier discovery (touching and dragging is a nice quick way to access an item but less obvious)
Combo widgets don't behave nicely if the current item selection is near the bottom of the menu, scrolling up is awkward, should show as many items as we can rather than lots of blank space when near the bottom of the list

Frame expose/hide gesture (swipe in from any screen edge, swipe out over any screen edge)
Hide keyboard shortcut hint accelerators
Hide/expose on screen keyboard. Show one or other, not both at the same time
Access Point device palette does not respond to touch events
