Hello,
Thanks for the Feature request. I think someone suggested this before, but
didn't actually submit a Feature request.
I have added your feature request to the projects file, and would like to
thank you care you took in preparing it, particularly for giving the detail
you did -- including links to MSDN, and for getting the formatting
(spacing, ...) correct. That certainly simplifies my task and facilitates
getting it into the projects file.
I think this is an important feature, and it merits some priority ...
Best regards,
Kern
