So what do you want to turn off? Remote editing? Or just the option to upload the changes back (i.e. turn editor to viewer)?
I'd just like to turn off the option to upload the changes back.
I don't mind viewing/editing files locally, but if I want to upload the changes back, I'll do so myself. I don't want to accidentally hit save locally (or worse have the program do it without my knowledge like Excel) and have the remote file affected.
