Because I like a clean editor, I hide pins not in use from my nodes. By chance I found that EU Blueprint graph also had a Hide Unconnected Pins button. However, it’s more like it deletes the all the pins from the node, as creating a new node will have no pins at all!
I discovered this by binding the Hide Unconnected Pins to the ‘H’ key, and trying it on a node from a plugin. The node that already had connections hid the unnused pins, but trying to create a new node had absolutely no pins.
Please make the Hide Unconnected Pins toggleable or add a Unhide Unconnected Pins function!
