Won't be able to do that too soon anyway. I'll do it in my Sandbox, so you can take a look at it first! Or most likely you'll get down to it earlier than me and the changes I had in mind will already be done... ;)

Strange, for me there are never underscores(I'm just typing  and the first few letters and then let autocomplete do the rest). But as you said, not really important, as both ways seem to work.
