Thanks for adding extra properties! I have a couple other feature requests regarding this feature.

1. Ability to search for images that don't have a certain extra property. Right now you can search for images that do have an extra property with the query "EP: X Contains blank value" but changing it to "Not Contains" doesn't work to find images with the EP "X" unlike tags, because not all images have the EP. Maybe it can work by adding a key for all EPs like "EP Not Contains X"?
2. Ability to search for the text inside EPs without going into the advanced search menu, like tags. Not sure if this is possible?
3. Keyboard shortcut to pull up extra properties menu, like "P" (unless I'm missing where to edit keyboard shortcuts, because I also lost the "T" keyboard shortcut for tags in the latest update)
