What does "re-arranger of the proverbial bookshelf" mean?

There is no proverb involving a bookshelf that would fit there. I get the feeling our Ingrid doesn't mind making stuff up for no good reason. It either doesn't mean anything, which it doesn't to me because I can't be bothered to think about some dumb-*** "poetry", or it means whatever you think it means, maybe she tries to figure all the permutations in her life, like.
