New Windows Version User Interface

[Ziyyigo-Tipyigo]

Or am I mis-interpreting the "multiple windows" thing totally and it's in reference to the chat logs?

This.

Basically, think of two separate log windows, each with their own independent set of chat filters. Say, one log for battle info, one for everything else (a/k/a the current default XIV setup).

Seriously, someone with PhotoShop skillz just needs to make a mock-up of the XIV interface on XI, to hold people over until Vana'fest.
