Playing through Skyrim SE with Lady Cora, I've got a couple of new mods which I really enjoy.
For player homes,
Skyfall Estate is a nice big estate near Whiterun (across from Honningbrew Meadery, which is good for my followers). You can build it room by room much like Hearthfire. It does have a few extras that I'm not crazy about (all those damn mannequins - I just don't build them). One thing I'm not crazy about is that when you buy the estate, it puts the entire house up. You don't get to build it wing by wing like you do the Hearthfire homes. I always liked that bit, since I can just leave them as one room homes and build around it (garden, animal pen and stable), and leave the other wings for later. Still, you have to furnish the interior, and it all takes in game time, so if you are playing with a Needs mod, you need to make sure you break for food & sleep.
Another mod by the same author is
Blackthorn, which I actually like better. It's a town you build where that southern road to Riften makes a horseshoe bend. You come across a little trading post, and ruined/burned out buildings. Talk to the trader, and you can start rebuilding the town, one building at a time. I like it better because it's more immersive, though it still puts up an entire building and then you spend in game time again to furnish each building. However, I save the manor home for last, as I role-play that it's important to get the town up and running on its own first. After each building is done, you can collect rent/income from each aspect of the town - trader, farm, mine, smithy, inn, bookstore, alchemist, and pelt shop. And there's a grounds keeper and a "citizen" that pays rent to live there. I think it fits more with Lady Cora's backstory as a lady of a holding. My only real peeve is that it is all the way east in the Rift, rather than more central like Skyfall.
I remember being annoyed by "Stupid dog" comments from my followers whenever I had Meeko or Vigilance running with us. They're good dogs! Meeko may be a bit silly, but he doesn't run from a fight! So I was happy to find two mods that work very well together:
Smart No More Stupid Dog Comments and
Immersive Good Boy - Dog Companion Praise. Now I can tell them who's a good boi! Especially when they look at me the way they do . . . And better yet, all my followers tell them "Good Boy!" which only makes for a better atmosphere at home.
A new mod which has rapidly become my favorite is
A Cat's Life. OMG is this mod everything I've always wanted in Skyrim! Not only does it add cats to all the settlements, it also adds two stores where you can buy cat supplies and even cats, and it adds interactive strays that you can feed, gain trust, pet and adopt. Once purchased/adopted, they will follow you (at their own speed, of course, but they will catch up to you eventually). They don't fight, which is a good thing because they are protected, but not immortal. They will survive attacks from hostile creatures/NPC's, but not accidental hits from you. Still, when things get a little crazy, I like that they run off a bit, and come back when combat is over. I've adopted three so far, and am working on a few others. The mod keeps track of the strays you've found, their disposition towards you, and which ones you've adopted, renamed, and which ones are currently following you. I've found myself stopping every so often (especially after cantering my horse along the road) to let them catch up, and whenever we encounter a hostile creature on the road I call them and pet them to make sure they're okay. I"m on my way to the Crazy Cat Lady title, as well - just one more cat to adopt!
