Hello Don,

Many thanks for your notice. As far as I understand your comments
below, this issue has not been rejected completely, but has been
put in the list of features to be considered for the next version
(can you tell me where that list is?).

If that's indeed the case, I don't want to follow up on this issue
at the moment.

Regards,   Martin.
