<p>A function I'd love to see in LR is a basic function in any database system -- that is a search and match system that would allow all images/files to be stored in an unstructured way and retrieved on the fly by any of dozens of criteria -- all taken with an individual camera, all taken with some lens, all taken at 0800-0900 in the morning, etc.</p>

<p>LR already allows you to do that with a series of parameters as the attached image shows. Additionally, the lightroom catalog is just a regular relational database (SQLite) which can be read by a wide range of applications, besides an SQLite viewer, by installing an ODBC driver for SQLite. The options offered directly in LR are just a small range of the possibilities with the data in the database. There are even tables for "Face Properties" so I guess we'll see face recognition in the next version.</p>
