From our latest PTR Patch Notes:

User Interface

  • You can now assign a specialization to an equipment set in the Equipment Manager.
  • An “Open All” button has been added to the mailbox.
  • You can now preview an ensemble set by CTRL-clicking it.

Spellbook
  • Spells that haven’t been moved to an action bar are highlighted in the spellbook.
  • Mousing over a spell highlights it on your action bar, making it easier to locate.
    Pet spells can now be dragged onto the player action bar.

Quick Join
  • Auto Accept: A setting has been added to allow friends and guild members to instantly join your queues without a confirmation. This setting is located in Interface Options -> Social.
  • Group tooltips now show the available roles and if auto accept is enabled.
  • Right click a Quick Join group to whisper a member of that group.


Please note that if you find a bug, it's best that you report it in our 7.2 PTR Bug Report Forum.
