-## Thank you for sending in a pull request, here's some tips to get started!

 - Before starting on some new big chunk of code, it it is optional but highly recommended to open an issue first
  to say "Hey, I think this idea X should be implemented and I'm starting work on it. My general plan is Y, any feedback
  is appreciated." This will allow other devs to potentially save you time by not accidentially duplicating work etc...
