It's very hard to adjust the table angle, and it's annoying that the game suggests I would be looking at the table in such many positions! :) The User Interface overall is terrible and pitifying!
Please take a look at how it should be done - find a copy of Celeris` Virtual Pool for MacOS 8 or 9 (warning - it crashes under 9 when Quitting).
They have the UI and everything - the best of class in any pool game on Earth on any systems - and believe me I've seen many pool games since 1987!

OMG if only Celeris ported their wonderful Virtual Pool under Tiger...I'd give my $33.
