I often have a need to create group templates in different projects that will do the same thing or nearly the same thing. Every time I make a new project I'm limited by not having all my templates, so a lot of work has to be done and copied in one home project despite the data being hosted in an enterprise geodatabase. I would love to be able to save group and feature templates as some sort of template file that I can import into new projects.
Could have an "export/import all" option like with Attribute Rules.
