I would try to avoid creating more columns. You know in many cases the text in the Comments may say "this book is similar to that book", and I would just enter the url to that specific book in rich text format.

Or the url can be used to do searches in the database.

I have been using it this way in the Content Server for long, and I would hope I can do it in the Main Calibre. In my view, it is simpler and more convenient than creating a bunch of columns.
