How to access things like spellbook and or just to get to default in game items . default things to adjust. is ther e like a /darkUI or some other spelling to get to the configurations pages etc..? I love it so far just difficult to find some settings or how to.

I did not even see it, thank you for pointing it out. I commend this UI very much, very clean install, very clean looking, very easy and straight forward to adjust in configs. Overall You did great, thank you ))

In game press esc to open game menu, there a botton named DarkUI, click it to open the addon configuration page.
