Good that this wishlist item exists, I already voted.
In the past, a Windows update made my FSX not to start anymore, re-install required. And what if I want to replace my PC? These are the things which can happen and I do not want to imagine assigning in MSFS all the key bindings and adjusting all the settings once again…
They either need to implement the export/restore function or make an official statement if and how the settings are stored in the cloud. I hope for many more votes!
