A click-to-grab / click-to-drop alternative to drag-and-drop, for people who find press-hold-move-release difficult.
An alternative to the complicated drag-and-drop mechanism. Drag-and-drop is difficult for people with dexterity or fine-motor-control difficulties: it asks you to click, hold the mouse button down, move, find the target, and only then let go. In children's software we see the same problem solved a different way — a "click and stick" mechanism, where clicking an item attaches it to the cursor until you find the target and click again to drop it.
The images below are both draggable after you click on them. To stop the drag, click again. The script has a setting in its init (click) to toggle between click-and-stick and regular drag/drop.
