HamdenPro: it would be nice to have the ability to be able to choose a specific hole as a single hole practice round.
Simple:
Take a time travel back a year (or more) - the Flash version included that option, with limitations.
There was a tab introducing all courses, and you could jump to any hole and play it, but only from one (forward) tee.
Since they omitted it in favour of the "three random holes practice", my standard statement may apply for any thought to revive it:
"They are WGT, hope is futile!"
HamdenPro: In addition, in practice mode, there should not be a limit on how many shots can be taken. As an alternative, you can allow the player to select number of maximum strokes in practice rounds, similar to selecting number of timeouts
That sounds awesome but it's contrary to
WGT Law §1: "The Player Shalt Not Have A Choice!"
