Actually I'm using them with accouting apps for example, to keep the data 
separate, accessed with a different user ID.

Even without GUI support for access management, which is on the wishlist, I 
appreciate having the fields editable by hand.

KDE#:
#81208 support right-click "start as..." different user for icons and menues
#81210 kdesu window should offer option (button) to start user management
