New Windows Version User Interface

[Ziyyigo-Tipyigo]

I am certain that I am not the only one thinking that, is it simply not possible to have more lines for a single macro?

What they mean is "We're re-creating XIV's Action Bar within XI." It's the macro buttons themselves organized in three rows, not that the macros have three lines of commands each.

In fact, in general, most of what was listed can be summed as "Aspects of the XIV interface are being implemented in XI."
