If I use "Edit Timesheet" to put time against a case, it doesn't show up as a case edit for search purposes.
If I have a filter of updated:yesterday updatedby:me it won't catch that I used "Edit Timesheet" to show that I put two more hours against casex yesterday.
Filters like these come in handy from a project management perspective because they help to see what was done yesterday to help drive daily stand-up / scrum meetings.
Since these kinds of edits get missed, we sometimes miss bringing them up. It would be great to have them included so we could ask "What did you do for the two hours you worked on casex yesterday? I don't see any comments."
I think would be as easy as having the same (or similar) case edit information as if the elapsed time was manually updated.
(I thought to enter this as I was giving my answer in Historical Data and explaining this behavior.)
