We noticed we are unable to edit the TO field to add email addresses after clicking REPLY as needed when on emails. Leaving us with the only option of adding people on CC is not good enough for us.
Using the FORWARD option requires one to start adding all email addresses on the trail manually which takes sometime to do in the case of when we have more than 10 people in copy and this might even lead to misspelling of email addresses.
Efficiency will be improved if TO field is editable once we click on REPLY.
