The default method of editing a position is called Quick edit. It's based on clicking on the point where you want to place checkers. The number of checkers placed on the point is depending on where you click, for example if you want to place 3 checkers on a point, clicking on the location where the third checker would go places 3 checkers. This method should be familiar to Snowie users.
Clicking with the left button places checkers for player1, clicking with the right button places checkers for player2. If you want to place more than 5 checkers, click multiple times on the tip of the point. To clear a point, click on the border of the board below or above the point - depending on if the point is in the lower or top half of the board. The bar works just like normal points - the more you click to the middle of the bar, the more checkers will be placed there.
