Quickly resizing nodes and groups

Use case or problem

Finding the edges of large or small groups/nodes to resize can be annoying and tedious.

Proposed solution

Similar to Alt+Drag’s resizing feature, add behavior so that holding Alt+Dragging (LMB or RMB, possibly configured in settings but I see no reason not to allow either) will resize the hovered group or node.
