P: Library module FIND feature suggestion

I have been redeveloping some old images, and thus the Metadata Date is updated. I would like to be able to search for all those images for which the metadata date is today but I'm seeing that it is not possible. In fact, being able to choose a range of time over which such a change occurred could helpful. I'd hope that adding such a feature to the metadata find choices would be fairly straightforward. Thanks. Thanks, especially, for such a wonderful program!

Perhaps generalizing things to allow the user to user to choose the metadata that they wish to search on would be the way to go.
