But they're not
They tell me more about my database and its structure.
Actually, I was rather pleased that you had left them there for users to enable, if they wanted them.
In my "Standard Layout" view I have them all turned on for max info.
I think I shall be making a separate request for you to enable some of those Column Names for users to perform SQL searches on, in the Virtual Folders.
For example, ClipFormat would seem to be the best identifier of whether a Clip is an image (value=1) or text (value=0). I currently don't see any way to get that distinction otherwise, anyway.
