To add what Aladire said, just think of the strain it'd put on the server if millions of players/characters were getting their UI saved. The files would be atrociously large and they'd need a server twice the size of the new one for NA.

Now if you want to fix your issue, just export your config on a usb key and bring it around to go to the cafe and at home and make sure to restore it every time you do a change.
