Hmm, playing aion has sparked an idea. Scott, how easy would it be to have it set up so that the whole of the bottom section can be moved to the top and the whole of the top part moved to the bottom.
Aion gives the option to have hud at top or bottom and it switches the player unit frame and minimap to either top or bottom based on choice. however, buttons always stay on bottom and target and target of target always stays at top .. rofl go figure. But the party frames are moveable.. rofl. Enough about Aion though.
OK, back to WoW and nUI.
In essence swap between them so that the base nUI comes with 2 layouts by default. One where everything is at the top and one where everything is at the bottom. That way people whos eyes watch the upper part of the screen are happy and those who like me watch the lower part are also happy
Then the little tweaks and customizations can occur to make it fit just right for the individual.
