Preflight Checklist

• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Describe your suggested feature

I would consider the idea of adding different auxiliary columns, like "pages read," "total pages," etc. (to your preference), similar to those in YACReader (apologies for the YACReader screenshot in Russian, I couldn't find how to switch it to English).
