I agree it would ideally work in remote view. Unfortunately due to the hacky and silly way I implemented it, this is not obviously feasible to me. The problem is that the mod interprets belt ghost placement as a signal to "extend existing belt". There's no way to tell the mod where the start of the existing belt is, if you never place a non-ghost belt.
I have in mind a different UI and implementation - one where maybe you have a special placeholder item or tool that does belt placement. But I'm not sure that will pan out, and I unfortunately don't have the time to work on it just yet.
