I believe you can control which "apps" require PIN access now. Been a while since I looked at it but I thought it was there before.
An enhanced Weather Time display would be cool, a little more forecast info maybe.
A configurable Event Notification would be sweet.
Assigning Scenes to Actions would be nice, I go with a workaround of recreating the Scene setup in a Rule currently. It works, but just assigning a Scene would be easier.
+1 on Sensor ReOrdering. It's annoying to the point where I might just delete and re-add everything...after I'm done buying sensors, whenever that will be.
