Our users request that the Task Description field (in Task Details, Overview) default to being open/fully expanded instead of having to click 'Show More'. User would only need to click to 'Show Less'.
That being said, our ideal solution would be that the task description appear along with the updates information. So, as you consider this request, please look holistically at the task user experience. There are multiple request related to placement/visibility related to task description, updates, reference number to improve UX and increase efficiency.
