There's some great stuff here @pedroparra , thanks so much for taking the time do it. Screen shot looks really good too.

I know @mmw has some changes he's about to upload as well. So maybe he could help review this PR?

@pedroparra sorry it has taken me a while to look at this. Nice addition 👍

Can you rebase master into this branch before we merge? Makes it more readable as to what the change is. I think we are done with the upstream branch as well, we need a process of PR into master and updating the versioning
