I was wondering if anyone has seen any instructions or a how-to for the WebOS 3.0 SlingTV app. What remote buttons do what, and tips/tricks to make surfing easier. And is there any way to get a multi-channel guide - meaning see what on now for more than 1 channel at once?

Here are some things I've discovered so far in my first day of messing around:
Up arrow brings up a guide overlay, where you can scroll channels why watching. Not the best I've seen as it shows 1 channel at a time only
Down arrow brings up full screen guide/menu. Again, not the best I've seen as its 1 channel at a time only.
Play/pause/rewind/forward buttons do work while watching

Has there been any info on whether they will bring DVR functionality to the app?
