In my collection of images, I want to create a collection of images that is limited to those that are large enough to print. i.e. I would like to exclude those that are cropped heavily enough that they are unsuitable for printing. I'm familiar with the collections module, but the metadata search field there only allows me to select from eight metadata fields (tag, title,description, creator, publisher, rights, color label, and geotagging). I want to search for "width". Is there any way to do this? I'm using darktable 3.6.
