What aspect of dashboard personalization can users NOT modify?

In the context of dashboard personalization within Pega, users typically have the ability to customize various aspects to enhance their experience and better tailor the information presented to them. However, one limitation users face is in the grouping of items by ID. This aspect is generally predefined and not subject to user modification because it involves the underlying data structure and how the system organizes and retrieves information.

The ability to modify the number of visible reports, the color of the dashboard background, and the size of dashboard slots are features designed to enhance personalization. Users can adjust these settings according to their preferences to improve usability and aesthetics. The capacity to change the grouping of items by ID, however, lies within the application's design and data management, thereby restrictively confining users to the established grouping set by the developers. This reflects the balance between user customization and system integrity in handling data.
