Just to be consitent with other ESRI web mapping API's, please add k
inetic scrolling (aka inertia scrolling) feature. On mobile devices, and, even on Windows 8, when you pan around on the map, the expected behaviour is for the map the continue to slide proportionally to the speed you dragged/panned the map. Perhaps the best implementation of this feature would be to ensure it is optional, perhaps in the map construct?
map = new esri.Map("map",{
"extent" :initExtent,
"allowKineticScrolling" : true,
"logo":false,
"fadeOnZoom": true,
"force3DTransforms": false,
"navigationMode": "css-transforms"
});
