Yes, it would be of interest. It would need to rely on Aqua/Quartz and
be written in Objective-C: unless something is done for the Quartz event
loop in command-line R (which is not impossible as the quartz() device
does so), it would be confined to R.app.
The main constraint is that we have very few people who know enough
about Mac GUI programming (and Objective-C) and R internals.
It was simple enough on Windows as we already had choose.files (and a
GUI for file.choose): that would also be worthwhile on a Mac. We also
