All suggestions welcome :)!
If you’d like to contribute, see the list of issues and pick one! Or report your own. If you have an idea you’d like to discuss, that’s always a good option.
If you are having doubts on the why or how something works, don’t hesitate to ask a question on gitter or via github. This probably means that the documentation, scaladocs or code is unclear and can be improved for the benefit of all.
