Minor issue doesn't impact use.
But I noticed when copying a device (ctrl+mouse click and drag) that the indicative outline of the device as I moved the mouse, included the arrow connectors which the source device had connected.
I panicked the first time .. but on releasing the mouse button the device copied as it should, the outline just confused me for a moment I thought had selected everything - not just the device on its own). I guess this is mimicking move behaviour , not copy.
In the attached screen grab I couldn't keep the CTRL key depressed and take a snap shot (so you can't see the + sign mouse pointer)
