I was wondering if there was any possibility of being able to place the cue ball where we like on the pracice table (as you would do on a real table)?

As this is possible from the break, would it be too difficult to allow it after, say, an in-off (or at any other time if it would be compatible with java)?

This would allow players to practice at will the shots they may be weaker in ...

What do you all think?

This has already been mentioned several times, and has always received positive feedback.
I'm sure Nick is already aware of this feature request, and that we will have it soon or late.
