Style improvements

Done along with @mollymcleod!
@fureigh It was feeling like too many numbers to me, with 30/90/365 already. Seems generally like last 7 days will be a pretty low number, and wouldn't necessarily add urgency to anything (especially if they aren't able to see what the calls are about). I was originally thinking of ONLY showing last 7 days if it's a significant number, like 4+ or something (so it's like an alert/flag and not something that's always there). My gut says take it out for now and if people ask for it or seem to need it when we test, add it back in.
