Yes. The "same" should now be possible with "current_filename", and
"browser.selection".

Well, the logic is really very simple, here: Whenever a script editor
window is "active", while starting the plugin, current_filename will be
set to the filename. Otherwise it's an empty string. Which may not even
have to be a show-stopper, as in that case the user could still select
some .Rmd file in the <browser>.

Note that for the sort plugin, there is a variant "sort2.xml" (available
as a "plugin under development"), which will additionally hide the
object selector, if current_dataframe is non-empty. After experimenting
with that, I chose to make sort.xml the default after all, as it shows
what's going to happen more clearly (object selector always visible).

No special logic should be needed for changing filenames in the
rendering plugin. You _might_ want to check for an .Rmd-filename
extension, and give a warning, if it's something else.
