[Chimera-users] saving sessions

on this regard I think it would be nice to have an separate option, when
saving a session, to create a self-contained session, which would
generate a directory containing the session file plus all the data
attached to that session. In this way you can take that directory and
move it elsewhere, send it to a collaborator, etc., knowing that you can
open it without scrambling for the original data (even after years,
given the great backward compatibility of chimera). That would be also
useful for archiving purposes (often a session corresponds to a figure
in a paper). Personally I would prefer the maps out of the session
files, even if it's true that you can open the session and save the file
separately (although it's a two-step process).
Just my rambling thoughts.
