Undecided on the button. Should it be text-only displaying "Show" instead of an icon?
Or text-and-icon? Is there a better icon we could use or is this one good enough?
Actually I played with that and in retrospect I don't think it would work. If we give it a "link-like" appearance, that would suggest that clicking on it would actually open the destination file/folder (i.e. the typical link behavior), which is not what we want here. We want to show it in the file manager, not open it. I'll stay with the current approach and change the icon as @ndavis requested.
