1. A computer-implemented method of managing touch screen inputs, the method comprising:

  • receiving a plurality of simultaneous touch screen inputs directed to a graphically rendered user interface element having an underlying, functionally connected first user interface control;

    receiving an additional simultaneous touch screen input that is also directed to the user interface element;

    identifying a first capture status that is assigned to the first user interface control;

    identifying a second capture status that is assigned to a second user interface control;

    utilizing a visual tree to determine whether or not the first user interface control and the second user interface control are related through a hierarchical relationship;

    utilizing, based on a determination that the first and the second user interface controls are related, the identified first capture status and the identified second capture status to determine a maximum number of simultaneous touch screen inputs that can be captured to the user interface element;

    capturing the plurality of simultaneous touch screen inputs to the user interface control based on a determination that the plurality of simultaneous touch screen inputs is less than or equal to the maximum number of simultaneous touch screen inputs; and

    filtering out the additional simultaneous touch screen input based on a determination that the additional simultaneous touch screen input exceeds the maximum number of simultaneous touch screen inputs.
