When we use the layout 'row' for emails, clicking a message opens it on a separate page and reloads everything. It feels slower and breaks the flow. Check out how Yandex Mail does it: the email expands in place right inside the list without a full page reload. You can scroll up and down and still see the rest of the list. It's super convenient, fast, and there's no need to hit back just to return to the inbox. Plus it looks clean and modern. It would be awesome to have something similar here.
