The theme I’m developing heavily uses the
square thumbnail type. However, sometimes the archive editors want to emphasize specific parts of the image. I see that you can use
local.config.php to specify that a specific part of the image should be used for cropping thumbnails. However, they want the ability to specify a different gravity value that would be used to override this setting for each specific media.
Is that possible at all right now? How difficult do you think this would be for a developer to add?
