Many plugins require add-on packages, e.g. XLConnect for the
(Java-based) Excel import plugin. If that package is not installed,
RKWard will prompt for the package to be installed once you click
"Submit". (Via the overloaded require()-function in R). Part of the
idea for this "installation on use" approach is that users will be able
to evaluate whether a certain plugin is the thing they are actually
looking for, _without_ having to install requirements _first_. Also, in
some cases, the requirements change according to the settings in the
Now, previews are not any different from this, in principle, except
they will "do stuff" before you click "Submit", possibly even as soon
as you open the dialog. This would defeat the above logic, and thus my
thought was that it is better to show a message "cannot show preview,
because package XY is not installed", rather than the usual prompt for
installing the package.
(In fact, in the current implementation, if you were to _not_ install
the required package, the preview would prompt you to install it again,
and again, and again, for every change you make in the UI).

Yes, sounds reasonable. Will see what I can do (but adding previews is
rather easy, all in all).

Yes, and that's really useful, too. My idea was that if the shared
"image" remained editable, this would make it even easier to "reply" in
the same medium, e.g. by posting yellow stickies, or moving elements
