Sometimes the animation leaves some clutter in pair or thread diagrams. Dragging stitches can resume the unfolding process.

Sometimes a pattern definition causes clutter. Dragging stitches can reveal what happens in a problematic area.

The draggable modus may cause nervous/rotating diagrams when trying to change thread colors. The modus applies to thread diagrams as wel as pair diagrams.

Very large droste patterns may not unfold properly. Wait until you are sure the animation is finished, then start dragging to continue the unfold process. The system may react very slowly, please wait until something starts happening.
