Filter contacts by recipient type (To / Cc)

[gravit8n]

Thank you for creating this add-on. It is really useful and works great!

I have one feature suggestion that could make it even better: an option to filter contacts by recipient type (To / Cc).

For example:

• To: contacts who were primary recipients
• Cc: contacts who were copied
• To + Cc: all contacts

This would be very useful when searching through emails and trying to distinguish between direct recipients and people who were only copied.

Thanks again for the great add-on!
