Which app data files do I copy into another library to recreate the look and feel but not copy the attached libraries?

I know about the plugins, tweaks, author and tag mapping, but what is the file that I can copy that won't give me a total clone of the original one.

I just want the same look and feel without it being an exact clone.

Also, if I do create a new library from an exported library database folder, is that the "same" library? I wonder if having multiple Calibre setups from the same export folder causes problems with library id's or some other behind the scenes identifyer that is getting mistaken when it reads that there are multiple instances of the same library.
