How does snapping work for Scale tool? When I try using snapping for scale it works only with Increment type (when Snap button is turned off and I keep Ctrl key pressed, with Snap button turned on snapping for Scale tool doesn't work at all). My question is: is there a way of snapping to vertex, face and edge while scaling in Object or Edit mode. Why does snapping work for Move tool and doesn't work for scaling? I don't believe that it can be so.
Changes have been made to improve the way snapping works.
You can now choose which type of snap affects transformations.

In the snap popover towards the bottom activate Scale to use vertex snapping while scaling objects.
