I’ve got a couple of suggestions for the Box Edit dialogue. First, love the ‘uniform’ checkbox - absolutely love it.
I might perhaps suggest you change the tab order for the size though, so I can enter X dimension - tab - Y - tab - Z dimension. At the moment the tab order is x - uniform - y - z. Also, could we have ‘enter’ to apply the changes?
Another little thing would be to change the default pivot location to ‘centre’ in XYZ - or at least make the location sticky so it remembers the last setting?
