title_body: How to add read status column in calibre? I want to sync my read status in caliber with my Kobo Auro H2O(Koreader) but it is not supported yet so the advice here is to create a read status column then sync the data to it.
  
  Can anyone explain how to do it?

  The option is available trough Preferences -&gt; Add your own columns -&gt; Add custom column.
