As a foolproofing thing:
It would be great if the Waveform widget (or any other widget that uses this) would indicate that a signal isn’t actually enabled in the Device Control.
As in: The waveform widget’s UI shows options for “enabling” the GPIO streams. However, if the IO are not enabled in the Device Control, it just shows a space on the graph where the IO signal should be, but it’s blank. It would be great to have a little warning or info-box stating that if I wanted to see that signal, I needed to turn it on in the Device Control panel (ideally with a copy of the Device Control icon as well)
