I haven't had the time to research the 'defacto' scoping behavior in the wild some more.

So maybe we should only vote on the folder order, as the scoping stuff really shouldn't be rushed.

I'm ok with:

<LDraw>\p
<LDraw>\parts
<LDraw>\models
<LDraw>\Unofficial\p
<LDraw>\Unofficial\parts

Given <LDraw> is a 'library', meaning you could have multiples of those.
