Feature Suggestion: Drag email to another email and attach as .MSG file when using search results

After switching from windows this has become one of the bigger headaches. Apparently I do this more than I realized.

Often I need to share a historical email with someone but it's part of a new chain. So it makes more sense to attach the email than to forward the email to the list of people (creating two email chains inappropriately). After searching for the email and finding it, you can't drag it to a new message.

In Windows, you can just Ctrl+C and Ctrl+V from your message list OR drag the message from the message list into a new email..

You can do this from your default view, but not after searching.
