If one Tech is assigned to many WOs at the same time - the bars reflecting single events (WOs) overlap and go into each others ... so, in that case you cannot really recognise in the console where a WO ends (you must enlarge the view and click on the event to see the end time, which of course increases the overall operating time.)
Ideally it would be if overlapping WOs should be displayed below each others and the bars would not overlap in the same row.
