Hi,
I am sorry for the delay in responding to this post, out of the three features that you have suggested one the option to set a default value for pick list is in our road map, the feature id for this is SDF-26693. The feature will be added to the application in one of the future hotfix. I have forwarded the remaining two suggestions to our development team and will get back to you shortly with an update.
Regards
