(Keep in mind that this isn't everything! Only what I can share as of right now. )
  • Patch 2.1
    • Focus targeting
      We'll be changing the focus target feature so that its display is set at the highest priority and also improving the visibility of the casting bar. At the same time we will also be expanding the areas you can click!

    • Teleport window
      We'll be making adjustments to the teleport window so that it does not go off the screen (mainly PS3 version). Moving forward we will continue to improve the teleport UI to make it easier to see.

  • Post-patch 2.1
    • Mog letters
      We'll be adding a history section for sent letters in the Mog Letter window.

    • Gear sets
      We'll be adding an icon to equipment that is included in a gear set to make it easier to distinguish.

    • Chat window
      We'll be making it so you can change the name of a chat log tab without having to delete it.
