New Message Input Layout

As someone who is left handed, my left thumb tends to start and lead actions on my phone: most notably, tapping the message bar to start typing. With the new location of adding images and file attachments, I'm CONSTANTLY hitting those by mistake, as they're on the far left, right where I'm used to tapping. Left handed users may not be a large percentage of the userbase, but it sucks to have this as an issue; more customization of the layout would be ideal, or even just a toggle between left- or right-side placement of these other buttons.
