Invested magic I think is the only one, here's a shot of my nexus:
The Lind's stuff kind of turned out too strong. I can wear a circlet, gloves, panties, skirt, top, scarf, and boots. I put spell schools and magic regen on em all and it turned me into a fireball machine. I wanted it mainly so I could see my sweet tattoos.
I've got skyui as well of course, though I think I got it through the steam workshop.
Flower girls is a sexy time mod. Have to be careful I don't hit any of that while streaming. It puts hookers in most of the towns, and gives you lovey options with companions and I assume spouses. I haven't gotten hitched yet in my recent save. I wish it had a bit more PG bits to it but you go kinda straight from first base to poundery.
Invested magic is neat. Anything with a duration is just about permanent, and it subtracts the spell cost from your magika total. So you can do summons and shields and such without having to constantly redo them.
The SkyUI group hotkeys are the best thing to have imho. The only thing missing is something on screen to remind you what you have bound. Hate killing the flow of battle by using the menus, it's so consoley.
I've got fireballs on 1, lightning on 2, dremora lord / trap soul on 3, forget what is on 4. C for health and V for mana potions (but I run out of one type and you have to manually set up more so I always forget).
F for fast heal both hands, G for heal other.
That sweet horse mod also has cool hotkeys like I bound T to a follow / unfollow toggle. Y is use nearby stuff, so you can pick plants or talk to people or loot without dismounting. H is fast dismount, which bugs out a few times when you first start using it but eventually becomes reliable. B I put on horse inventory.
Random mining is a must. Lets you set up how many swings you want, how much ore you want per node in a range, or it has a whole progression system with more mining the more smithing skill you have. I went lazy and just have it give me 10-20 as fast as possible.
The anime shouts are comical. I need to see if there are any other decent shout voice replacers. The default female sounds like Zarya or something.
I've tried a few companion mods. There was a super cute Korean girl that was a great archer, and pretty smart AI, but she was just talking constantly. I didn't mind so much at first but she would start blabbing loudly when I was trying to talk to someone else. Just blabhalbalbhlhablhablhbahlblhabblhlhab all in Korean I had to turn her off.
Harkeeth I don't use as a companion, but he is a shopkeeper with 2000 gold in the drunken huntsman in whiterun, so I kept him just so I could sell crap to him.
I went through all the pain of getting all the physics to work. It looks really good on some hair and flips out on others. Butts jiggle about a bit too, and hilariously Lydia's boobs bounce in her steel plate armor. You can fix that sort of thing with that outfit studio but bleh I'm too lazy.
