Did I imagine it or does 14 / 15 introduce the ability to add content trees into the back office?
I know older versions did this in some way, but i'm sure this was mentioned with a different use case for Umbraco 14/15.
I was thinking this would be more for storing Settings Data, or a Repository, so that the main tree is only for website nodes / pages.
I can't find it mentioned anywhere, so maybe I just heard (or misheard it) at UK Fest
