Groups or users hidden by pagination are too easy to miss on page administration : rights pages

When administering a page rights and more than 10 users or groups are to be displayed, this fact is easy to miss and having to navigate between pages can be a bit dull.

It has confused me (several times) especially when a bit in a rush or tired.

Suggestions to fix this:

• The text I circled in red ("Results : X out of Y"  and "Pages : 1 2 3 ...")  could be made easier to spot by making it bigger and darker
• The user be able to change this number of users / group per page.
• This default number of 10 could be raised (to 50, or maybe 20?)
• a sentence at the bottom of the table could warn the user about not all elements being shown.
