Content Providers and Flat Content
A classic challenge in many CMS - and also in Episerver - has always been what do you do with large amounts of non-hierarchical/flat content? There has been many workarounds along the way and I was just on my way to make yet another when I discovered a well hidden secret deep in the belly of Episervers UI: The Asset widget (that holds blocks and media items) does in fact have infinite scrolling - which in turn can support incredibly large flat structures!
