Thanks for your reply, I’ll gladly answer:
I refer to the Setting Rights Pages which you encounter for example in the Admin Menu or on setting rights on pages themselfes:
There is no option to show more than 10 results.
Our use case is for example creating new groups and then setting rights to a page similar like other exisiting groups. Right now we would have to go back and forth between for example results 1-10 <–> results 31-40 and dont have an overview at a glance.
If we use the filter, we would filter out the groups we want to set and also cant see multiple “target”-groups at once if they dont have similar names. So we had to back and forth between typing in the group we want to see, delete the string and then type in the group we want to set.
Another use case is if you have more than 10 groups, you cant see the standard-groups “XWikiAllGroup” and “XWikiAdminGroup” at a glance and have to navigate to the end of the list.
I know this is just a small issue and only a comfort one, but I thought I’d add it because it seems to be an easy improvement (I hope 
)?
