Overall, the product is great! I love how in the timeline you can right click to easily select the different mouth shapes for syllables. That being said, it's still a bit restrictive, as I can only zoom in and out of the overall timeline. I can't use my mouse scroll wheel to expand a particular row vertically. Basically, I would recommend adding all the usability perks of timeline manipulation like you can find in Premiere. It would make it easier to see what you're doing while editing each frame in depth.
