I have the Griffin "official" dock and it's not worth $30. It works find with the SUPCASE but I find the phone too easily rocked back and forth when docked. The dock feels like something you would buy off Ebay for $5 w free shipping from China. Okay maybe not that cheap but you get the idea. Daydream works well. Haven't noticed any notifications though. I don't think any come across when in daydream.
Edit: By default when you put the phone in the griffin dock and daydream activates there are no active notifications displayed. I only see the clock on the screen with the notification sound. If I tap on the screen it makes daydream go away and the screen goes black. Once I do that, new active notifications start showing up. I haven't tried anything else since I like daydream and prefer that mode when docked.
