Expand email by clicking in grid row
Currently, when browsing emails, the user has to click the "+" icon to expand the row and read the body of the email. That "+" icon is a small target for clicking. I'd prefer the same behavior be applied to anywhere within the grid row. Click the row, message expands. Click the row again, message collapses. No change would need to be made to the existing behavior of the "+" icon, just add the same functionality to the row itself.
