  • Add a custom column directly from the addon preference window to show any mail header you want.
  • Set the default columns settings for any new folder.
  • Show hidden columns in the Conversation Tab.
  • Edit a mail header value for a single message.

How does it work?

After installing, open the addon preference panel to:

  • Show or add custom columns.
  • Set which column show in a new folder, and choose how to sort the messages in the folder.
  • Choose which columns you want to always see in the Conversation Tab.
