Those nine little buttons to the left of XY coordinates.

They seem to secretly reset themselves to middle position whenever I let go of an object and come back to it.

How I hate that feature! Why?
Because 5/10 times I tend to make numeric size changes to objects via that width/height input thingy and most always I would want the size change to happen from top left corner of the object, not from the middle because then I always have to reposition the object.

Please make object origin point a configurable default setting in the Options panel!
