I have spoken to a few people who have had the same idea as me. when we add time tracking to a ticket (manually or running time tracker) we have to go into the item updates and refer to the time and date and then update it with the task we were working on. This is sort of double work as we add the time and then have to type the time to refer the update. It would make it much easier if there was a text box whenever you add time manually or stop the time tracker that can reference the work done to the time booked and feed the info into the update section.
Looking forward to hear from you,
