This is critical to the practical usability of the mobile app: I have an email thread that is currently 10 emails long. On the desktop/web app this is fine, it's threaded/grouped and I can expand and collapse it as needed. But on the mobile app, since I can't collapse it at all, these 10 emails take up the entire inbox screen and I have to scroll more to find emails. I should be able to expand and collapse in the mobile app the same way I do in the desktop/web app.
