A problem I've encountered while using the Agile process on my Experience Builders is that there is not a way to share a draft build with non-editors. And since I already have an approved and published version, I can't make draft revisions and share them with anyone to review. Basically, if I really need to make some major draft revisions, I have to copy the entire app and work in the copy.
Just having a way to either bookmark certain "app configurations" or "states" so that you can come back to them if needed, or even just making the "preview app" link shareable with your core or content groups would be a big help.
I hope that makes sense.
