There is a mod allowing you to quick-cast spell without having to equip them, it's called GRHotKeys. I've tried it and works perfectly, well I only tried it with Magelight and Candlelight yet, I don't know if holding down the button works when casting Flames for example.

I don't know if it has been made yet, if so please tell what's the name of the mod. I'm looking for a mod that, if possible, would make both my equiped one hand weapon appear on my character when sheated. As of it now, only the weapon equiped on my right hand would be sheated on my character. Does a mod doing this exists? Or do you think it would be possible?
