Hey Patrick!
Thanks for your contribution! Adding default was one of the open tasks discussed in #53. Would you like to tackle the other once as well? If not, just let me know and we can go on with the current PR content ;)

Hi Thomas!

Unfortunately, I don't know the other ones. I always work this way: I'm figuring out the things I currently need (which is mostly of course just a small subset from what is available), and if parts of it were not documented, I directly open PRs with the content I just figured out to prevent that others run into the same issue. In my opinion that's a good compromise between being an overall maintainer which is quite time consuming or, the other extreme, not contributing anything at all.

So you'll may see more Mini-PRs by me in the future that'll improve stuff bit by bit :-)

Thanks @pfink for both your PRs!
