Fancytree Drag & Drop - Advanced Example

Native cross-tree copyTo
Native cross-tree moveTo
(Non-)contiguous multi-select using modifier key (Ctrl/Opt)
Drag & Drop reorder of nodes from the same tree (multi selected)
Drag & Drop single or multiple selected nodes from left tree (including lazy-loading)
Native support for multi-node DnD (currently implemented using the std. callbacks):
- includes multi-node helper image
- Also sometimes the order is reverted.
Native support for multi select with Click + SHIFT and CTRL (currently implemented using the std. callbacks)
SHIFT: Only inside the same parent.
Also, Click + Shift could allow to extendb> a current range.
Prevent dropping from left list to the active node
Update a counter and send an ajax request on drop
Currently we also implement a 'pill' or 'badge' on the line item that shows how many sub-items are in the folder, they are similar to these Badges - http://twitter.github.io/bootstrap/components.html#labels-badges.

Images inside nodes are scaled to 16x16
Drop target marker should consider the real node height
(Non-)contiguous multi-select using modifier key (Ctrl/Opt)
Drag & Drop reorder of nodes from the same tree (multi selected)
Add Fancytree-like D&D target icons to Sortable list sorts so they look the same as Fancytree sorts & drops
Optimize CSS for better disambiguation of 'Selcted' vs. 'Active' nodes
Suggestions welcome!
'Nothing is droppable on the right side (though the right is multi-selectable and sortable within itself)'
QUESTION: shouldn't it be possible to drop from the gallery here?

Click one Sortable list item to highlight it, then Shift Click another item to select multiple contiguous items in Sortable list [like your OS does]
Dragging a Draggable over the right tree does not revert, although invalid
Make Sortable --> no working solution yet, so the should not be a MUST HAVE
