Sometimes when logging work you may want to know how much effort you have previously logged for the current issue. There can be company specific restrictions like not charging customer more than an pre-agreed work hours (in that case adding a second duration field to log work dialog is better idea) or other reasons. WorklogPRO helps you with this problem right on the "Log Work" dialog. For example in the following screenshot, the user has already logged 2d 5h 32m of work previously for the issue ERP-3.
