One thing I just noticed is the the tick boxes add some content to the PR. It shows "9 out of 16" on the Pull Request list. That seems to mean 9 out of 16 tick boxes are checked. I guess github things tick boxes are used for a list, not to pick one of several options. Anyway, I don't think it's a big deal at this point, just wanted to point it out.

Looks great to me

@apcraig I'm not sure how to get rid of the task numbering without entirely removing the checkboxes. But maybe we just shouldn't worry for now? We can see how this works for us for a bit and make changes as needed.
