Allow to create small mailing list groups
It would be super helpful to create a group, like "Summer Vacation" or "coworkers" or "in-laws" and then add people to that group so later when I want to send an email (e.g. forward a photo from my phone I just took) to that group, I do not have to first save the photo, then look for the latest email to find the thread, then add the photo & send it, or manually add every recepient all over again, hoping that nobody is left out. It's such a simple thing, I don't understand why it is not yet possible... It's like creating a contact with multiple email addresses, but the contact name is not a person but a group.... So it doesn't even appear to be a difficult upgrade...
