I've read that the Arch Mage's Quarters aren't all that secure. Sure, you had to jump through flaming hogsheads just to get the key, but everyone else there has it, too. I'm always finding Nirya on the stairs to the quarters. Apparently the other mages use the place for their own uses. Having said that, I tossed the staves from the end quests into a footlocker and they're still there.
I like Breezehome for smithing, plus the central location. Apart from that, though, it's rather primitive and limited in scope. I'm tinkering with remodeling it with the CK. Actually, I'm using Uthgerd's house because, though smaller, it's more "up market" lol.
Put too much into a container and it becomes laggy. I'm thinking of shelves with small sacks arranged on them, each with a category, like "small sack of soul gems," or "small sack of ingredients A-K."
Oh, and your manniquiins move around sometimes.... on their own. Spooky.
Honeyside, right? Those guys get around. Scares the bejeebus out of me sometimes. Found one at the enchanting table the other day.
I put a gate on the outside so the bear can't get back in and also a forge on the outside. I can fast travel to the shack and find everything that I need within a few seconds.
LOL, that bear is going to be so mad... You'll probably kill him and find a lock pick on him.
