When editing user's permissions it only lists 10 different sites per page. This is quite inconvenient. It would be much more convenient if the pagination was configurable.
Furthermore it might be a good idea to have some kind of "universal" pagination where any pagination was configurable. This would seem like a lot of work but would be a permanent solution for the numerous pagination issues opened over time.
Users -> click "Edit" for a user -> go to "Permissions" and then permissions of only 10 sites is shown on each page.
The page is very "loose" with a lot of whitespace between the rows, so most screens probably only fit the 10 sites/rows each screen! Anyways some people would prefer to scroll rather than click between next and previous page many times.
