Display output when re-compiling R markdown?

[cpsievert]

It seems you've made a conscious decision to not display output when re-compiling R markdown. Would you be opposed to adding that option? I think it's helpful to see what's happening during interactive use and for debugging purposes (in fact, imo, that should be the default).

I'm already working on a PR, just want to make sure you agree...

I don't know. It does not look like something of which I can make a decision in two minutes, so I may have to take a look when I have got time.

Hi, I really love this package! I often use it to show my results in the Viewer panel in Rstudio. I would second @cpsievert and hope you could consider adding a function to refresh the results automatically. And it will be great if the viewer panel could scroll simultaneously with the source panel!
