Sorting and Searching on the User Administration Screen in System Manager

larger implementations tend to have many users. The user admin screen in system manager is very difficult to use when you have to manage 200+ users. Can it please be made searchable (search by username or first/lastname or email for example) and also can it be sorted to show "last modified" date at the top or bottom? Currently (Jedox 6.0 SR3) when a user is modified and the save button clicked, it jumps back to the top of the list. if that user was somewhere near the bottom of that list you have to again scroll all the way down to the bottom to check your changes.
