Hi adambroderick,
On every one of our lesson pages, you'll notice a green bar at the top. You can click there to get to the new lessons page. The new page puts the notation side by side with the video itself you can see. Some (not all) song lessons will have automatic notation scrolling so that the notation moves as the song plays. Check out the new lesson page above each video by clicking the message in green.
As far as strum patterns go, our notation does not currently include it, but that's a pretty good idea! I'll pass it along.
Thanks for the feedback, and I hope this helps.
