Well, one simple thing would be: .Net integration.
I mean sure we can have Shawn's great Kixforms.net but again we'd have to depend on him for the updates, besides, it only added Forms. I even wrote one myself once, but stopped development because it's all in PowerShell. And the last year I've come to the point where I'm using PowerShell because KiX couln't handle the tasks I needed it to do anymore without .Net functionality.
