 * Hello,
 * What is the best way to modify your plugin? Without loosing changes after upgrade
   or update.
 * For example: I would like to add additional custom button inside “entry detail”
   page next to: “Move to trash” – “Print” buttons. With additional functionality.
 * Any guidance or advices are welcome.
 * Sincerely,
    Mintaras

 * The safest way is to buy VFB Pro and use the vfb_entries_detail_metabox action
   to add your own buttons.

 * That sounds great.
 * Does “vfb_entries_detail_metabox” action is listed in documentation?
    I could
   not find it (at [http://vfbpro.com/hooks/](http://vfbpro.com/hooks/)).
