Open email in new tab / window?

Is it possible to open an email in either a new Android window or in some kind of K-9 Mail specific tab/window system (like Firefox’s tabs)?

I read lots of email newsletters and it’s frustrating that I lose my place when I have to quickly open or reply to a new email.

I just set up K-9 and tried long pressing and looking through various menus, but hopefully I missed something obvious. Otherwise, the app is really snappy and fast on my old Android device, so thanks for all the hard work!
