I think the first solution (context/options argument) is the clearest and simplest. Yes, it's a bit verbose, but: - You can use the 'view' and 'viewWithOptions' pattern where the former calls the latter with a default primary color etc., so you can get convenience if you don't care

I think there's truth in both positions. Elm is unstable and that's part of the fun, but we need docs for people who didn't experience 0.16. 0.17 is a groundbreaking release, not a polished one. In the meantime we should collect all the docs we DO have and see if that's enough for Mark. --

Yes. It is definitely related to the subscription. I have a large simulation that drains laptop batteries if I keep polling for events when the program is paused. That is why I keep subscribing and un-subscribing, to save customers' batteries. On Thursday, May 26, 2016 at 9:57:46 AM UTC-5,
