I would suggest adding as many sportsbooks across as many states as possible, including some of the same books in different locations. It's good to see that the personalization settings are looking to come back in the future. While I was not a big user, I can see how that could help some users narrow down the books they want to use.
But you need a large selection of books to narrow down from and I suggest you start building relationships and expand those columns and increase the value of logging in to the user.
On the odds side, highlighting changes should be a priority. Spread and Total combos can be very convenient and should be added in as well.
But a major use of the SBR odds page can be as a scoreboard and many like that play by play data. I think it should be an option that could be toggled to "off" in order to condense and make page just odds and scores, like it is now.
Sorry to see classic odds go, I truly am.
I will forever miss that "beep" going off throughout the house when SBR reported a move, even if there was a small delay on that reporting. Saturday mornings were so much fun with that and even my kids got into it when they were younger.
Good Luck with further development on the odds page guys.
