Please add back the ability to toggle on/off visibility for these other columns:
* Lists -- show the list sets that an article occupies
* CiteKeys -- show the citekey for the article
The first will improve the ability to cross-check whether duplicates are scattering in different places. The second will allow me to avoid having to export to BibDesk (macOS) to check the integrity of cite keys from a library that is to be compiled into a document via LaTeX.
