Prior to Bug 37398 if you had the date accessioned plugin setup on a date field 3 small dots displayed to the right of the input. If you clicked on these I would replace the date in that field with today's date. Some librarians would like to see that functionality restored.
+1 - We definitely would like to see this restored!
If you leave the field empty, it will automatically save with today's date (not saying we should not make it more obvious, but that might help)
