I guess max vote filter would not be necessary because there's max pending payout filter already.

I'd also like to add the post value / average rewards value, but it's little bit difficult because average values are calculated asynchronously after the post fetched. I'm not sure if I have time to work on it soon because I'm too busy with other projects these days.

You're very welcome to contribute on github ;)
