If you click on the information icon from the category bar on the Plan Screen, you will be taken to that category's details screen. Though these screens will show up in the navigation as the Plan Details screen when selected, they are different.
On this screen you will see the title of the category selected at the top of the screen and the measurements and tactics tabs below. Within these tabs, users can see all of the measurements and tactics tied to that category. To the side, you will see the category's summary.
If you'd like to edit the category summary or name, click on the Edit button on the upper right-hand corner.
Note: To delete the category altogether, click the 'X' icon from the Plan Screen.
