Is it a common thing that so many witnesses are powering down?
Nice upgrades to the stats I'm accustomed to from steemian.info! Looking forward to see what else is still on your to-do list and hasn't made it yet to the tool.
UPDATE: I have an idea for your list of last 50 witness vote 'movements'. Can you add a filter by MV? While all votes are important, it is more significant usually to see the changes of votes from accounts with high stakes (or with large total MVs proxied by them for witness voting).
UPDATE 2: Same as above, but another filter for votes of other witnesses.
I will do my best to implement some of them.Thanks for your feedback and suggestions @gadrian.
