Additional sorting for Observing List

I originally submitted this (incorrectly) as a trouble ticket for a suggestion to add more sorting capability to SNP7/SNP+7 Observing Lists.  It was suggested to post to the Community Forum for discussion so the developers can gauge interest.

Specifically, what I'd like is the ability to sort my Observing Lists by Constellation, as I often do most of my planning by constellation.  Would anyone else be interested in such a feature?  Sorry, don't know if this is the best way to write this or if I should include more info.
