 * Mobile: think UI layout so that fingers do not block the view (right and left handed)
 * Mobile: display tooltips larger and on the side of screen where the finger is not

 * AI: apply safety distances to move actions
 * AI: do not always move first, they are defenders
 * AI: add combination of random small move and actual maneuver, as producer
