Hello handsome and intelligent developers!   I have a small feature request. Currently with the node tool, when editing a shape, if you single click on a line between 2 nodes, it adds a node. This is super useful! But i notice that a double click on a current node does nothing at all.   Double clicking a node with the node tool to delete it would be a great use for this currently unused action, and just another way to make the node tool a left-hand-free tool (since right now, to delete a node, i have to click it and then remove my hand from home row to hit the delete button).   Let me know if you think this is a good idea!
