1) Why master has so many folders like controller and model, do they relate to jquery++?
2) Aren't there plugin that would make content of the element unselectable? Now write my own that sets css properties like MozUserSelect and webkitUserSelect I thought it would be good to have it in some standard library.
2) I thought selection was disabled for draggables. Could you create a jsFiddle example that demonstrates your issue?
