I started playing Midas Magic recently. The mod is what it's cracked up to be. It's very cool, adding over 290 spells to the game. The downside to all these awsome spells is that it can be really annoying to search for a spell in that huge long list. Out of curiosity to see if I could / for fun I made a mod that allows you to change 'spell books'. It lets you 'hide' all of your midas spells or all of your non-midas spells so you can navigate shorter lists.
Then I thought: Man, this would be cool to do for Morroblivion.
This mod that lets you hide all of your oblivion or all of your morrowind spells. You can also show either group by school: meaning you could show all of your morrowind conjuration, alteration spells and all of your oblivion restoration spells. This would let you do something that seems to me to be at the heart of Morroblivion: letting you play the two games more seperatly while still being able to transfer back and forth at any time. You could use only morrowind spells in morrowind and still have your cyrodiilian spells for when you returned to the mainland...
Here it is as a completed mod. (I'd love testing feedback). I'll message David and see if he wants to add it to the esm, but I assume it will just be a mod.
Cheers!

That sounds like a neat idea.
That sounds like a neat idea. As an optional mod this would be pretty cool. I think you should go for it.
