I would like to suggest changes to the 'Group Management' section.
When trying to sort in Group Management, if you have multiple pages, it will only sort per page. If I try to sort by 'Last Seen' I have to go through every page and select the items. It does not show the sorted objects from all pages.
Another option would be to allow for more endpoints to be seen per page. Somehow having a dropdown asking if you want to view 10, 20, or all endpoints per page. This would get rid of the issue with the sorting.
