R-devel/src/library/grDevices/src/qdCocoa.m at 37:

#define histsize 16

so, yes, it is hard-coded in R.

It is not part of the R.app GUI but actually of the Quartz device in R itself so it is not configurable.

It simply saves display lists and replays them as you go back - you can do that with any device that has display lists enabled (see dev.control). I'm not sure what Rich is up to but you can always save and restore plots with GEcreateSnapshot and GEplayDisplayList regardless of the device and the display list is just an R object. Keeping more than 16 plots seems a little tedious to go through ...

Cheers,
Simon
