Con Odd UI interaction conventions
Some conventions used to interact with the software are either questionable or simply going against what's commonly accepted. For example, right-click + drag will move around, holding down the right-click will open up the context-menu and left-click in an open space will start a new unconnected node. What this results in is constant accidental opening of context-menu then accidental creation of a new node trying to get out of the context-menu.
