Good shout on the feature list on the README, thanks. In the meantime, there's some additional detail at https://statusnook.com to that end.
Honestly, I'm not sure about PR's yet. To prevent any disappointment I'd encourage discussing any changes before beginning work intended to be upstreamed. I should include this in the README.
Could you maybe make a feature list in the README so it's easy to see if it supports what I need myself?
And, do yo accept PRs if they're good quality?
