It would be nice to be able to rename Waystones. After exploring a bit I have multiples of several waystones with no way of knowing which is which. ...and with the long cooldown on the Warpstone it makes the Waystones a bit useless.

Shift-right-click them, it brings up the naming GUI.

Ah, it doesn't work if you have torches in your offhand. That was my problem.
