Visible UI User import creation
The Upload button stays active after you’ve clicked it, allowing multiple clicks because you don’t know whether it is running or not. There’s no UI feedback to the user that the upload is actually running until it either fails or completes.
so, it would make sense for clients to actually visually see the users being imported on the UI level.
I would also suggest that the user record displays the date it was created, updated and by whom. (I’m seeing duplicate user entries and cannot determine who created it and which was created first.)
