I think it would be quite good if we could add a CSS class to fields within the asset layout setup so that we can easily theme just individual elements.
At worst case, it would be great if the class "field-xxx" could be added where xxx is the name of the field.
Further to this, it would be great if we can possibly change the output HTML generated with templates.
For example, if I have a field called xxx, it would be great if I can control the output more - e.g. For an asset link, I would love to (on some assets) be able to output each link on a new line as an ordered/numbered list.
