Currently, the email subject list displays the timestamp on the right side. This changes to action icons (mark as read, move to trash, etc.) when the mouse is hovered over the message.

The problem arises when the list is narrow because the divider was dragged to the left or the browser window is not full screen. When the user moves the mouse to a message title to open and read it, the icons suddenly appear over the title, resulting in unintended clicks on actions.

Proposed solution: do not change the UI on hover. Either never hide the icons, or never display them in the email list at all.
