Re: Request for pointers and advice: displaying several buffers inside a single window

[Yuan Fu]

Following mode plus atomic windows seems doable. But it wouldn’t be 
transparent, AFAIK follow-mode needs to add special handlers for things like 
isearch and query-replace. OTOH, it would be much more difficult to implement 
in xdisp.c. I wonder if there is an intermediate layer that’s higher level than 
redisplay (in lisp, or at least not in redisplay) but still more or less 
transparent.
