The Dashboard view cannot be customised currently. We do have plans to allow you to do that but for now, it's designed to provide a quick summary of the stats in an easy-to-read format, and all on one page.
If you want to see more detailed information, you can export data from relevant sections such as Manage entries, Users, and Orders. See Exports overview to learn more.
Each table is limited to a maximum of 50 rows. This means the Entries by category table will only show 50 categories, even if you have more.
