Hi huys:
where can i find the vector fields button so i can directly controll the particles and simulations with ease?

Ha, that is a good one. Just use all the buttons.

But seriously, art directing simulations is an art all to itself.

What problems are you having that seem to be out of control in your current scene? You will have to give some example description of your scene and explain what part is not in your control that you would like to control. Then a solution can be cobbled.
