I tried the demo - great work! Looks lovely and feels really solid. There are a few things I would change...
The ability to get the camera down lower?
Ability to walk around and see table from any angle before shooting?
Rather than balls just disappearing, make them fall into the pockets? (Just a nicety but would be a nice nicety!)
AimHelp: Show where cue ball will go?
AimHelp: Show where object ball will go after bouncing on other balls / rail?
AimHelp: Show where cannoned / planted balls will go?
Options for different camera moves during shot? Stay with player / Follow cue ball / Follow cue ball then follow object ball...
