I've just started playing with the program as well.
I must be really blind because I missed a key feature, which I have only just stumbled on.
There's a button on the immediate left of where each player's equity is displayed. This gets enabled once a board has been provided, and on clicking the button we get to see a new form which shows the player's relative hand strength. I saw an example of the form in the first post but couldn't figure out how to open the form until now.
As a result, this program seems to be a good replacement of both PokerStove AND Flopzilla. Very impressive that its been made available for free
