I hope not too OT, but is the NSUndoManager recommended (by others 
building apps with CCL) as the undo infrastructure for our lisp 
stand-alone application built on Cocoa?

I have rolled my own undo system in lisp (no doubt not as efficient 
or robust than Apple's) but in everything I hope to minimize MacOS 

In particular, sometimes I need to make undo start persistent between 
boots, and fear that I'll struggle to do that with the NSUndoManager.


As an aside, I have very many questions of this kind which are not 
core CCL issues, but more CCL with the MacOS or Cocoa.  I feel there 
must be places for lisp people to discuss things, but assume that 
forum may not be on openmcl-devel (I'm sure that Clozure folks know 
everything that I could ever need or want to know, but are too busy 
for my sort of muddles), the Apple Cocoa-dev list is perforce lisp 
unconcerned, perhaps other lisp forums?
