A counter would have to be increased with every load of a page; this wouldn't necessarily be difficult to implement, but it would have *no* rate-control. It would literally increase for every single click. There would have to be some rate-limit, such as by IP, but that's an area where NNF is lacking (no database). It's something I've been noodling; but without outright embracing a database, I'm not sure of a simple, reliable solution.

The question you need to ask with any such feature is "how do I rate-limit this?". You can't just allow anonymous votes, bots could go mental with it. You'd need to create a file of votes-cast for each user; this in itself wouldn't be that hard. But at that point, I don't think NNF is what you want or need -- it's way too limited for what you want and you should really use something more capable. NNF only suits those who really *don't* want view counts and votes and so forth, NNF was made specifically to _avoid_ those! :)
