Short: it would be great to be able to save default alias to be chosen when writing to a particular recipient.

Explanation: I use Airmail for three main accounts: work 1, work 2, personal. If I can send a personal mail with a work account (it won't harm) contacting a work 1's customer/colleague with work 2 alias could be awkward so a contacts based way to select optionally a default alias for a specific recipient would really help me in this. Also a forced "check before send" option that throws a popup asking to choose the alias before sending would help (or a "null" alias default that inhibits the "send" button).

Thnak you very much for reading this.
