Currently, two points are connected by an arrow. This arrow is defined by a direction, a speed and a time. This results in a 2d vector. This should be extended:

• Make draging points possible. From the new point positions, the direction can be calculated easily. However, speed and time are not so straight forward as there are infinite solutions for a specific arrow length if both speed and time are variable. For this reason, there needs to be a locking mechanism for speed or time, and only when one of the parameters is locked the point can be dragged
• Enable position locking where the arrow length and direction is fixed. Then, when the speed is changed, the time parameter is calculated accordingly to result in the same position. When the time is changed, the speed parameter is calculated accordingly to result in the same position.

Thus 3 locking mechanisms are required: Position, Speed and Time.

Instead of having a map open side by side it would be cool to have the open street map in the background. It should be possible to have exactly the same arrows as they are until now.
