Auto-fill the sender field with the relevant mailbox sender for new messages/emails
Auto-fill the sender field with the relevant current mailbox's address - rather than having to scroll through the drop-down to choose the correct sender. This enables quicker composing and accurate "from" sender address placed in the message. I have accidentally sent stuff before from the "default" sender unwillingly because I forgot to change that field. If I am replying to an email, the "sender" field goes in automatically, as it should. It would be nice to have that functionality for a new message/email as well. It would be like this: Mailbox-XYZ is what you have in your mail window - now instead of clicking the new msg button and having the "main box" mailbox as my sender - the field will now auto-fill with Mailbox-XYZ. Do you follow? It's a bit hard to explain with text. Easier to show someone.
Interesting idea. I will need to discuss with my business partner and the development team if and how this wold be possible to implement.
With the recipient, as you enter anything, the list of options from the address box that fits gets narrowed down.
