Hello Wayne,
Thanks for bringing your concerns to our knowledge.
We try our best to bring most the features our users ask in our common platform, but sometimes it happens that sellacious is providing you your 95% wishlist but rest 5% needs some manual coding efforts. For point no 2 & 3 are the same kind of wishes, unfortunately, these are yet not available in sellacious, if you want we can develop this for you at no extra cost once you acquire your premium license (annual and above). once developed it will be available for all our users.
