Sometimes you may want to know how much effort you already logged for an issue while entering a work log. WorkLogPRO displays that information directly on the "Work Log Dialog", next to the "Time Spent per Day" field. For above example we have already entered 2d 5h 32m effort for ERP-23 issue.
As said on the bottom of the dialog you can open "Work Log Dialog" by just pressing 'w' key. If you do this on an issue page, issue is pre-selected on the dialog; if you do this on a timesheet table, issue will be empty and you need to select issue yourself. In both cases "Date Started" field will be populated with current date and time.
All other features of JIRA's own work log dialogs are also available of course.
