I've seen this as well but learned to live with it. It'd be nice to get the same (primary) completion on every selection though.

The Vis:insert function inserts keys at all cursor positions of active window. I copied few lines from digraph.lua and it is working with multiple selections and also in replace mode.

Just replace this line with that:

	if vis.mode == vis.modes.INSERT then
		vis:insert(out)
	elseif vis.mode == vis.modes.REPLACE then
		vis:replace(out)
	end

PS: This only works when the prefixes of all selections are the same

Thank you for the hint, I extended on this in my PR. It will only autocomplete those selections which share the same prefix as the primary selection, the others remain unchanged.

I'm not sure if this is a good solution for everyone, but it would work for me.
