Power List View Status
Within your Power List on the ECH, pressing the "View Status" button will show you a table overview of the tasks completed by each user group. This table is searchable and sortable, and you can filter by tasks completed. If you add separate booking costs, these will also appear beside the respective user group, and are not marked as completable.
User Updates
You can also view the activity of your Power List through checking "User Updates". This will provide a list of the recent updates users have made to tasks, so you can see who has checked and un-checked which tasks in the app.

Generating a PDF report
You can generate a PDF report to view the status of your Power List offline. Press the "Generate PDF" button; this will also apply the filters you have set for the status table, including the user updates, which if checked, will appear at the bottom of the report.
