Had a brief look on the Nexus and google but didn't turn up much.

I'm wondering specifically if there's a mod to make spellmaking a "do it anywhere" kind of process, similar to enchanting and alchemy.

I'm picturing a mod where you'd need to have some particular piece of equipment - a spellmaker's tome, say - and equip it on your character to bring up the spellmaking menu, just like equipping a soul gem or alchemical apparatus will bring up those crafting menus.

It would also be cool if you needed to have certain components in order to craft spells.

Say for a Destruction spell effect, you needed Fire Salts. For an Illusion effect you needed... well, I dunno, but you get the gist: each school could be represented by a particular "ingredient" that would be consumed upon the creation of a spell. These requirements would make the process a bit more interactive and interesting.

Not sure if something like this exists or is possible.
