**Within a resource - A large field for "Notes", not just a single line. We are switching from KeePass, and have used the notes/comments field there to store procedural information about specific resources.
**Search - All Fields
**Attachments. Another feature in KeePass that was very handy for attaching service contract info, etc. This could be put in place in liu of a larger note field as said above.
Other than some of the minor things, I love the product. It is robust, and serves the purpose of much more expensive tools at a much cheaper cost :)
