As an Estate Owner / Estate Manager, when you select the World, Region/Estate, Teleport Home One User or Kick User From Estate, you then have to type in the name of the user and do a search for them. You are also presented with your calling cards from inventory.
My experience indicates that when you have to remove an individual from your estate / region, you want to do it fast and odds are it isn't a friend so you won't have your calling card. Having to take the time to key in their name and do a search, then assuming you got the name right and it doesnt have four or five numbers at the end of a common name, you are finaly able to use the tool.
What it should do, is when you select either Teleport Home One User or Kick User From Estate, is present you with a list of all the users who're actually on the estate / region at that moment. Then you can select the name from the list and deal with the problem in about 2 seconds instead of 10 or 15.
Additionally, although this is something extra, it would be nice if those options (teleport home / kick from estate) appeared on the pie menu when an Estate Owner / Manager right clicks on a person while on their estate. I know the Freeze/Eject options are there for landowners, but they should be there for estate owners / managers also.

World - Region/Estate - Teleport Home One User and Kick User From Estate should list users On Estate instead of calling cards
Just to make it clear how difficult it is to ban someone in the heat of the moment, consider this user story with me as the protagonist and Some Jerk being a griefer filling my sim with penises.
1. I show up. Some Jerk is filling my sim with penises.
2. I get all pissed off and more than a little worked up.
3. I click the world menu.
4. I click Estate...
5. I click the Access tab on the far right.
6. I click Ban a user.
7. I flip out for a minute and check my chat history to figure out how they spelled their name, and if they've already teleported home by now, I desperately try to catch one of their penises in edit mode so that I can get their name, and if I can't do that, well, I'm screwed.
8. I type their name in and click search.
9. I click their name, making sure I don't simply click "Ban" or I'll accidentally ban the first calling card in my inventory!
10. I tell it whether I mean this sim or all estates.
So, barring the whimsical steps above, I've had to perform about 7 times, not counting what it takes to get the person's name. Then I need to run around and try to return all of their crap... I can return all SCRIPTED items in the sim owned by them, but that takes yet more of the interactions above. In the mean time, all of my users are watching penises dance across their screen, because I can't ban someone in less than 30 seconds.
I imagine that trying to get a list of everyone on the entire estate would probably be a computationally expensive operation. Even just listing people in the current sim would be a great improvement. As Atashi pointed out, chances are that you don't intend to ban a person whose calling card you have... and as I pointed out, the DEFAULT selection is the first calling card you have... I've accidentally banned my friends before!
