Explain the problem as you see it
I have a particular usecase where I tag certain nodes that contain fields with images (or is an image node itself) with something like #photo or #memory. When using an instance field that is set to this supertag, I sometimes wish that I could look directly at the picture instead of having to crawl through text.
Why is this a problem for you?
Sometimes a node's primary content is its image, not the text. It would be really nice to be able to select according to its primary content.
Suggest a solution
Perhaps allow an instance field to display in the dropdown menu according to one of its fields (then I can set it as the image field). And also display it like an album, so I can select it.
