For a long time when you install WorklogPRO you get some build-in timesheets on the main WorklogPRO menu:
Weekly/Monthly Project Issue
Weekly/Monthly Project User
Weekly/Monthly Team Issue
Weekly/Monthly Team User
All of these timesheets actually can be replaced with a custom timesheet which gives more options to users, like ability to add extra fields, filtering for attributes etc.
*Starting with this release we are replacing them with equivalent custom custom timesheets. In a feature release they will be removed from the main menu. But users will able to add them to their own menu if they want.
*This will be mostly transparent to users. Only difference will be displayed "Period Selector" component. Instead of week or month picker a custom timesheet dialog will be displayed when they click on period button.
