fix screen resizes on help screen
add equivalences, so I can finally clean up the harddisk mess
  (and soon have YES/no instead of 1/0)
experiment with group edit mode
write more regression tests
use sets in demo (but where ?)
add wrapping of long lines
document KCONF
clean up terminology in SCEND doc (e.g. active/enabled)
do performance analysis
get rid of screen&cursed
improve mini-menu

change data structure: (maybe ...)
  consider turning choices and sets into presentation attributes
    + cleaner design for choices/sets
    - bools and ifs get a second identity
  make values ordinary items
  allow values to be if'ed
  add display list layer
  then add some screen update prediction to display lists
  make summaries "flat" (-> cycles /= 2)
  allocate tokens on input -> only pointers
  then store length at ((int *) ptr)[-1]  (well, maybe not ...)
  allow expressions for defaults
    ints will be fun ... maybe process range violations of actual value at
     end and all other errors (default out of bounds, low>high) immediately
    choices may become a problem too - what if multiple values default
     to "true" ? check also immediately

maybe later:
  add list type
  use group common configurations in demo
  skip over "dead" entries (e.g. comments with no section)
  switch to YACC and LEX
