I don't think this exists already, but...
I'd like to request a way to resize an object without it affecting other objects. Perhaps holding down ALT or SHIFT while resizing, would allow the user to resize that object without affecting properties of another. Sometimes resizing can be a pain if you've done a lot of placement of objects already, and then have to remove a bunch of PackSize/Location properties to resize something.
I know the way selection/de-selecting items is changing, so any hotkey would do really. Hope that made sense
