One thing I don't quite get though is whether it
is
safe/smart/possible to use a description editor on the hard-coded
descriptions (eg. change priority; add more options to an
MASingleOptionDescription).
No, this is not save, unless you copy them before editing. If you
flush the description cache (and this happens automatically if you
edit your code), they will be flushed.
Btw, I did not forget your mail "Magritte: Error when adding Multiple-
Option, Single-Option through editor" however I couldn't fix the
problem yet. Stay tuned.
Cheers,
Lukas
