Some 'bite-sized' possible improvements for the teleportation UI:

1. Currently, right-clicking on a waystone presents a list of destinations to teleport to. This list includes the waystone that was clicked on (meaning you can essentially teleport in place), and there's no indication of the current waystone's name.

It'd be handy to show the current location as text above the "Select your destination:". Additionally, the current location could either be removed from the list or simply disabled. (The latter probably is the better UX practice)

Example:

Current Location: Seaside East

Select your destination:

  Seaside East
[ Seaside West ]
[ Itaiksa Village ]

2. There should be a client setting to show waystone coordinates (next to the "Current Location" text for the current waystone; if any, maybe as a mouseover? for the others), and a corresponding serverside setting to disable that client setting.

First point sounds good and is being added to the next version.

As for the coordinates, I don't really see the benefit it adds and I'm not the biggest fan of displaying "internal" data (such as coordinates) during normal gameplay. I don't think it's worth the effort.
