Any list of TODO items for people to contribute?

I've been having some unhappiness with the API design of https://github.com/ReactiveX/RxGo, so finding this implementation has made me quite happy - I much prefer the trampoline scheduler over the use of hidden goroutines, as I'm interested in using this in an application where I need to ensure certain actions occur in the main thread.

I see that this library is still pretty young - I'd love to contribute. Do you have any TODO items that are documented, that I could help to implement?
