I did try the counting thing, but couldn't get it to work.
I admit though, I did stop when the next step was to create a new type
kind of thing that I could use for counting. That seemed to start going
down a deeper path than I was hoping for.

However,
I am hesitant to go and try anything else because everything I've submitted
so far has been NACKed. The only thing Russell said he'd agree to is a top
level single-platform option. But, since that all got taken out, I assume
there's some resistance to putting it back in.
