If you're node editing a selection set by dragging the bounding box bars, both sides of the bounding box move in or out from the reference point. In standard selection editing, only the side being dragged moves. For consistency and capability, both modes should be available in both edit modes, perhaps with a toggle key or option check box to enable/disable. My preference is a toggle key.
I'm also reminding developers about something that's been asked for occasionally over the years: a key sequence finish like Alt + F for those tools that have only been given a "finish" flag in the context/right-click menus. I can't recall all of the tools that have this, but generic transform is one of them. Generic transform actions can be completed after indicating one pair of before-and-after features, or two or three. Three pairs finishes the action automatically, finishing with one or two pairs has to be flagged. Assembly-by-three-points has the same behaviour, and the same finish flag.
