In a way, this expansion was a big boon to storage space for me. I've cleared up about 150 storage by combining SoTs (yeah, I had a lot). I've cleared up about 100 more so far by unraveling junk I had sitting around that realistically I'll never use...I expect to unravel about 200-300 more items by the time I'm done.
That said, more storage is always good. Personally, I'd like there to be a way to buy storage add-ons in-game, so that even small houses can have substantial storage...I've always preferred small houses aesthetically, but I have an 18x18 just for the storage (ok, I realize I could have built a slightly smaller one, but still, you need a pretty big house for max storage). I'd hate to have to get a keep or a castle...they're ugly.
But yeah, +1.
