Another way to open the study log
In addition to “Study History Data” in Settings, the list button at the top left of the Study tab opens the same history.
Fields you can edit
You can change the subject, start time, end time, duration, and recorded date. Entries created without the timer are identified as manually added in the list.
Deleting an entry also removes it from chart totals. Create a backup before cleaning up a large number of records.
