Please make hint level adjustable.

This is a very good chess program. I liked very much the clarity and the simplicity of the display, without those distracting or noisy effects found in other chess programs.
I would have given it five stars if the hint level were adjustable.
What I mean is the following:
Under (SETTINGS --> HINT TOOLBAR BUTTON), the user should be able to choose the time, in seconds, during which the program "thinks" before indicating the hint.
