We could do something similar,    by ColorForth   having  two find methods:
* The first is the method currently  used in load, a list of masked cell 
names. associated to code address.. ( fast find  for load)
* The second method would be  used in edit,  a list of  pointers to 
names in source associated to code addresses.  ( indirect with masking 
find  for edit )
      Edit would   load  source using the second method,   building 
three lists:  macro,  forth, and  names not found in   macro or forth 
(define);  after each  User change in the source..
This would allow   expanding   or contracting   source in an outline 
format   from each  name in  list (macro forth  define ).
    Words  in source  not defined yet would show up in the define 
list, as simulator stubs.  When a stub is executed: display data and 
return stacks with possibly  associated source and allow accept  to  
record   and execute definition.  until  the  user is satisfied  with 
definition.  Then continue.    When  the user is finished the words in 
the define list  would be on the load block for the new  application.  
When this load   block is then edited    all the words would be in the 
macro or forth lists and the   define list would be  empty until  a word 
is redefined with a word not currently defined.  
   Words that control    would   need two different load blocks,  one 
for load and one for the editor to simulate the control in a safe way 
for simulation (user responsibility).

PS .I need some one  to  implement the   indirect name list  compiler 
and find   for us to implement this editor. I am to dyslexic an 
distracted with  other things  to implement this myself  in the current 
colorForth.  I can  test integrate  and advise on this project if  you  
all  can provide  source.
