JWKAUFFMAN  I'm a long time user and fan. The only feature not included that has ever given me pause... the absence of nested folders.

Otherwise, I've found it extremely useful.

When I first heard about it's release I thought I'd have no use for such an application. I purchased it originally to take advantage of it's product serial number tracking and password storage.

Since then it's been my catch all for info found on the web. I store recipes, receipts, coupons, OSX hints (like those handy keyboard shortcuts I can never remember). And a .Mac account makes Yojimbo shine. Syncing with my other macs has been flawless... and a Godsend.
