When the Keybase Client starts, it will add the KBFS volume to the Finder favorites sidebar, regardless if it's been manually removed before. I haven't found any way of disabling this behavior, and it's rather annoying as-is.

There currently is no setting to disable this. We need to add one.
The Finder favorite is removed if you quit the Keybase app (and is added when Keybase is started up).
IMO just that it keeps putting it on the top is my main objection; perhaps an intermediate solution could be to add it to the bottom? I'm not sure if that's possible.
We need to add [a setting].
Maybe this is what you mean, but I think it'd be enough to just keep it removed from the sidebar if one removes it, and then they could add it back (possibly via Keybase, or just via Finder as with other volumes).
We now remember the position of the finder favorite.. So if you move it to last item it will remember. We'll also have a setting for this soon.
