Something that would be super helpful is adding an option to position multiple items as a group using the x- and y-position inputs. Obviously you can reposition a selection of items as a group with mouse and arrows, but adding the options to use keyboard input would be helpful.
You can also solve this by grouping/framing the items, moving, and then ungrouping… but that’s a pain.
I see this feature as equivalent to the “align as group” feature that already exists using the shift key!
