np, if there is one thing I know, it is live line screens. The more I started thinking about it, the more I realized that you dont have to look as fancy as SBR, because your lines will probably be more accurate. While their screen looks great, the lines are somewhat suspect.
My next list would be:
put some cell padding on the game rows so that the changes dont bleed together on the home and away odds.
link the matchups to the team column so you can quickly view theRX stats from the lines page.
archived line moves shouldnt be too tough since you already built the changes infrastructure. I would make that open when you click on the odds themselves.
Other than that it looks good. At that point it will only be missing 1 thing... a link upselling G&J for the guys that out-grow your free version...
