after that, we can rename RKWard into aRsome :-D
unfortunately, i couldn't check it out yet, too many projects ATM.

sounds good. but wouldn't it be more useful to have split windows to be able
to move the preview to a second screen?

i'd assume that most people use v2 nowadays, because RStudio defaults to it.
it would be best to support both v1 and v2 because they are partly
imcompatible and it would also be confusing if only a fraction of your
documents is supported.
in RStudio you can add "<!-- rmarkdown v1 -->" to your source file to force
the use of v1. that's a policy we could adopt, so there's no need for further
configuration or complicated rendering options.

sounds reasonable to me.

RMarkdown v2 depends on pandoc anyway, so if we'll support v2 then we can
assume that as a given (and the debian package dependencies should have it
on rendering more MIME types: good idea as long as there's an obvious relation
to R in the context of RKWard, e.g., rendering LaTeX in the form of SWeave
documents sounds reasonable to me. for normal LaTeX documents we should not
risk to make people assume RKWard wants to act as a proper LaTeX editor like
an option to render .Rd documentation would be neat for package authors, using

that would lead a way to having one output file per script. i like the idea.
can we also merge this view with the plot device, somehow? instead of split
document, RKWard could get a designated preview section with tabs.
