Image textures for custom tags.

I am not sure if this would be possible to add, but with my knowledge, I think it is.
Simply add an optional setting for a display image on custom tags.

For example, if you were making a tag for all types of fish, you could set the image for the tag to be a created or imported image. This would replace the basic tag icon when adding the tag to crafting recipes, with whatever you set the image to.

Though this is a small change, it would make it easier to differentiate which tag is which without hovering your mouse cursor over it and reading the name of the tag.
