User List display in web browser - make Sort order consistent

In our NC18 instance in the web interface the url to the Users list is like
xxhttps://SomeHOSTNAME/index.php/settings/users
That sorts by Username, case insensitive

Listing members of a Group has url like
xxhttps://SomeHOSTNAME/index.php/settings/users/SomeGroupName
That sorts by Username, case sensitive

At very least, please can that be harmonised!! (on case insensitive)

(ideal world provide clickable column headings so lists can be sorted in different orders, filter by values in each column - but that is a more substantial feature request)
