Do you mean more than 41 models?

I would say that more than a couple of dozen models per GUI 
session is going beyond the design limits: with that number of 
models you want a script, or set of scripts.  But I'll take a 
look.

Sessions are in fact saved as a single compressed file.  Open 
sessions are also represented by a directory containing the files 
you mention: the "save" file is a compressed archive of the 
directory in question.  (I guess I should make these directories 
hidden so that people won't get confused.)

Wait a minute: Are you saying that if you save as "session2" the 
session won't open again?  (Never mind what's going on in the 
background -- just concentrate on things at the visible level not 
working as they are clearly supposed to work.)

I guess this might be feasible for PDF formatting on a landscape 
page.  I judged that 6 was about the limit for on-screen 
legibility.

I agree that the session concept is not fully exploited at 
present, and that is something we will come back to and 
re-examine.  Thanks for the suggestions.  Right now we're focused 
on particular econometric functionality (the bootstrap and VECMs) 
but the UI does need reconsideration.
