How to Edit a Contact
You can edit almost everything about a contact except their email.
Do this by going to the 'Contacts' section of Blitzen (accessible from the left-side panel).
Click on the arrow icon to the left of a contact.
Click and type directly into the fields you wish to edit. (Name, job title, location, age, phone number).
To edit the company click 'remove company' and subsequently 'add company'.
To attach a note to your contact click the 'Notes' button on the right hand side.
