Renaming a dead-end. Upon selection of the dead-end you are presented on the current map the dead-end displayed in yellow. After selection the presented list of dead-ends gets resorted causing you to lose track.
I suggest once the dead-end is selected for editing, that the selected dead-end in the sorted list stays highlighted, matching the dead-end presented on the map until saving. This will eliminate the confusion caused by the quick resort of the dead-end list.
