- Tap and hold on a performer, then click the trash icon to remove that performer from that Stagebook. He/she will be removed from all charts. - Dragging students onto the stage from the Off Stage areas will now force other performers in that Off Stage area to shift up in order to fill in the gap. - Slight performance enhancements

Partnering: Choose your side! The performer icon that you drag into a partnership now latches to the right. Fixed issue where changing grid view to "Always" prevented performers from being dragged. Other various bug fixes.
