Most amazingly, this setup is also unexpectedly resilient against merge conflicts and can sync even when two copies have changed. You wouldn't expect that from tools relying on 3rd party file syncing.
I still try to avoid it, but every time it accidentally happened, I could just merge the changes automatically without losing data.
Ok, now I kind of want this. I only have my PC connected to the TV, so I only need the power button, volume controls, settings and the D-Pad. A specialized cover would make hitting the right buttons in the dark much easier and also remove the ads disguised as buttons.
