Defualt UI questions

[Behemoth100]

Hello all, forgive me if this information is already out there somewhere, but I'm struggling to find it (watch someone embarrass me with a simple google now) but I'm wondering just how flexible the default UI is, for example:

How would I display multiple hotkey pages at once?
How (if possible) can I make the spell bar horizontal?

I'm not even sure if this kind of thing is possible, will I require a UI mod to achieve these things or is there a resource somewhere out there explaining the possibilities of the default UI (which I am actually rather fond of)

cheers,

Arthuin the enchanter.
