Ok, maybe the bounding box calculation is fast, and the bbox might be useful also for other things, so it shall be... (how generous of me! ; }
My point is,
BoxEdit should allow numerical inputs also in an object's LOCAL space, besides WORLD or CPLANE.
Ok, you could set the CPlane to the object, (which can be a bit of a hassle) and set the transformation center in BoxEdit (restricted to min, max, center).
But why mess around when the Gumball already can represent an object's local space and center?
Thus the wish for an additional GUMBALL=LOCAL mode in BoxEdit.
In fact, we can already numerically transform an object in local space - by clicking the Gumball's axes and entering values. Consistently, the same should be possible in BoxEdit, where the practical SIZE parameters exist, too.
Btw.: the regular move, rotate and scale commands all correctly update the Gumball. Nice!
And: I just saw the CPlane command has an option 'Gumball'... nice, too!
So, almost everything is in place... except a few BoxEdit options.
