Session Length Online Reader
The session length of 30 minutes of inactivity before you are automatically removed from a title is too short to really be able to concentrate on your study work. As a user, it is exhausting to look for the spot where you stopped every time your session ended throughout the title.
Might it be possible to make the session longer or to set up a pop-up window so that you are at least warned before the session ends?
