Needs more nesting to categorize more efficiently. I'm using Datavault and the top level is Category with Type under the and then the Items.
So, under Financial I have Banks, Brokerage, Credit Cards, Retirement, etc... Then under Banks are all my bank accounts with account number, login information, PIN, etc...
I suppose I could use titles like Financial/Banks and on, but that's an awkward work-around. Having top level categories just makes it easier to find things and have like items clustered together in a logical way.
