It would be better to make it possible to fix this guy and save his display position data.
It's annoying to be positioned near the center of the screen (It's somewhat left-leaning, though), and have to move it around every time.
（In other words, when relog-in, their position information is initialized)
Storage (chests), Equipment preview windows, etc.
These guys aren't yet compatible with certain add-on (SaveUIPos), so they must be controlled by the client body itself.
