A neat feature for Voat (as some of the subs are pretty community focused) would be to automatically keep track of things like a user's SCP/CCP or even number of comments or submissions.
Because then you could, for example, automatically 'reward' people based on their contributions or participation.
In other words, if someone gets 1,000 SCP in the sub then you could automatically apply a flair to their username. Alternatively, you could automatically make them an authorized submitter. You could have things like username flairs that are like military ranks, so people go up through the list.
This may increase participation - 'cause who doesn't like rewards for contributing? It may even be used creatively.
I could see a feature like this being useful in the v/guitar sub, for example. When someone new comes and joins the weekly guitar threads, they eventually earn the rank of 'n00b' and then they can work their way up to 'master.'
I could see it being useful in gaming subs, or even v/traditionalwives as a way of automatically rewarding/denoting people who have been active contributors.
And, best of all, it'd be easily automated. Just keep track of the SCP/CCP/number of posts and drop in a fairly basic sub owner/moderator control panel.
You see similar with some of the forum software, actually. The more they post, the higher their ranking goes and it may also confer extra features as the number increases. I could see this being a way to encourage more community participation for those subs that are more about the sub as a community.
Hell, @clamhurt_legbeard would have a field day with it in his AIDS sub, SDBH. SBBH would even use it, but not very well and it wouldn't ever actually make any sense. The gun club sub, traditional wives, FPH, and other such subs may all find that feature handy and find creative ways to use it.
