Reply-to

Dear madam, sir,

I use the explicit reply-to field, and it always defaults to my default sending address.
It would be great to have it default to an address connected to the From: field. Using that same address would already be a huge improvement. Ideal would be to have the default reply-to address settable per "Sending as" identity.

As things are currently, every once in a while I forget to set the Reply-to field (expecially when replying myself), and the reply ends up in the wrong place.

Thank you for considering this, and thank you for offering this great product!
Biep.
