Putting a star next to the name and marking the retainers on the map with a red dot is nice - definite improvement! But I'd rather have the search filter out all the other retainers completely, leaving only the retainers with the item I'm looking for visible. It would make finding the retainers in a cluttered ward much easier. Even with the red dot, I'll still have to walk slowly through the whole ward to get them all to load up on the screen to find the red dots.
I think once people stop cluttering a single ward this wont be an issue.
If you have every frequented even a busy ward that has proper retainers in it, they all load at the start and it isnt too bad(even with dozens of retainers in it)
the problem right now, is that the "main" wards people clutter into with everything they own have easily 200 retainers in them in some cases, and thats just too many to load at once. when 150 of those easily have nothing that ward is even supposed to support.
