I actually requested this in January 2018, and was told it was being considered. My original note was:
It would be super-nice to be able to create Nicknames for devices... I have the multiple device option, and so create flight plans on various devices. But my "Sync" screen shows 3 Windows devices (2 of which are valid, the 3rd was de-registered (how do I get rid of that?))... but unless I go back to a device and see what it's named, I can't tell from "Sync" which device is which. So, for example, instead of "Windows uklrxwxthhpt", I could give it a nickname too, so it would read "Windows - Surface Book, uklrxwxthhpt", or "Windows - desktop, ujlrxzxthhpt", etc.
