Ability to create a spatial view inside of ArcMap in the Geodatabase Admin Toolbox, post 10.1. There is some fantastic functionality in GDB at 10.1, but not the ability to create actual spatial views. These are still done via cmd line. I can create database views, I can create query layers, I want to be able to create spatial views similiar and as easy as creating database views in ArcMap at 10.1.
