[Clear Part Connections Hotkey]

To reduce tedium when removing or replacing parts it would be nice to be able to remove the parts connections first to avoid deleting everything connected to that part.

[Remapping Editor Controls]

Mainly because I find the rotate and zoom controls both being mapped to the mouse wheel to be at odds.  You should be able to zoom in while having a part selected.  Currently it creates a lot of tedium in moving/zooming the view while building as you have to constantly deselect the part to zoom.

[Two Connections]

I understand that it's difficult to do.  I think it is needed for this game though, so creations don't feel so rubber chickeny.
