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, on Android 4 after not using the trackpad for a few seconds the cursor is hidden again, which works quite well (erikos)
Palette hover/click behaviours
- Single tap of a button with a primary action should _not_ trigger hover delay palette content (to prevent toolbar palettes and help hints obscuring UI after use)
- Touch and hold _should_ trigger full display of palette content (like a right click, no extra delay)
- Tapping an icon with no primary action should instantly open the full menu/palette, no delay (e.g. Frame right edge buddy icon/s)
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)

Frame expose/hide gesture, swipe in from any screen edge, swipe out over any screen edge
- Hide Frame gesture would need to avoid being interpreted as a canvas scroll (will need tuning, probably a combination of touch start edge proximity and gesture speed)
- Need to consider Frame vs. page turning gestures, left/right page turning would need to avoid screen edge to allow for Frame gesture
Hide keyboard shortcut hint accelerators from tool buttons and palettes
Hide/expose on screen keyboard. Show either the Frame or on screen keyboard, but never both at the same time
Access Point device palette in lower Frame edge does not respond to touch events

Instantly open the large central buddy XO icon palette when clicking/tapping
Add new grid layout?
Maximise Activity icon size for finger friendliness
Disable Activity icon dragging for fixed layouts, or fully implement feature
Activity palette start rework... (temporally might want to remove primary start action and just expose the full palette on click/tap)

Remove primary action from AP icons (prevent accidental connection to random APs)
Remove primary action from ad-hoc icons (prevent accidental connection to random APs)
Invoke full ad-hoc, AP, Activity, Buddy palettes on single tap
Remove primary action from shared Activities (prevent accidental join of a shared activity)

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

Favorite star hit target too small to easily touch
Confirmation alert dialogue needed for Erase toolbar button (to prevent accidental data loss)
Confirmation alert dialogue needed for Duplicate toolbar button (for user feedback as to the action)
