Entering Work Log on Workflow Transition Screens

The add-on provides "Log Work Custom Field" that can be placed on any JIRA screen, including workflow transition screens. Using this custom field, instead of JIRA's own 'Time Tracking' field allows you to log work using WorklogPRO add-on that means you can enter work log attributes. Add the custom field to JIRA screens and remove the build-in 'Time Tracking' field. 

Functionality of this field is very similar to 'Log Work Dialog', you can refer to that section for learning more about how to enter work logs.
