The option can currently be activated from Virtual Desktops Settings -> Advanced. A better home and preview would be better for these settings.
In more detail, this option can make a wallpaper, larger than the geometry of the zone, scroll appropriately with each desk change. Consider a nice panorama picture, which is as wide as the total desks' width. Then, at most, E will scroll the background by 1 / (number of desks) for each desk change. The direction of the scrolling is dependent on the desk change itself. Also, the user can specify a coefficient of maximum scrolling for each axis. If the coefficient is 0, the wallpaper will not move.
More advanced animations can be constructed with edje. The data item "directional_freedom" "(1|0) (1|0)" can toggle the actual wallpaper scrolling done by E for each axis. A message with the current x/y position, panning w|h, and zone w|h is sent to the background edje with each desk change animation tick. An example embryo script that handles the message, and changes a hypothetical "a1" part in the "e/desktop/background" group is shown below:
public message(Msg_Type:type, id, ...) {
if (type == MSG_INT_SET) {
new x = getarg(2);
new y = getarg(3);
// new max_x = getarg(4);
// new max_y = getarg(5);
// new w = getarg(6);
// new h = getarg(7);
custom_state(PART:"a1", "default", 0.0);
set_state_val(PART:"a1", STATE_FILL_POS, 0.0, 0.0, -x / 4, -y / 4);
set_state(PART:"a1", "custom", 0.0);
}
}

Show Desktop Names is not enabled. Currently, any changes made to the
pager module config require the pager module to be restarted (or E
restarted). This should be addressed before a 1.0 release.

If you deactivate screensaver (ie: move mouse) or unlock desklock
within some given threshold, ask user if he would like to enter
presentation mode or even if should increase timeout to next event.
This is also useful when at the office and you quickly move mouse in
order to keep your explanation. If you know your explanation is short,
just hit "increase timeout", otherwise "Yes" to increase timeout.
Increase timeout is a multiplier that will increment the factor on
each dialog answer.
There is an option to stop asking. This can be changed in "Advanced"
versions of screensaver and desklock dialogs.

This option will make it possible to lock the screen after some
seconds screensaver started.
It is useful in cases you want a short screensaver and uses screenlock
but often need to unlock it quickly (ie: was talking to someone at the
office, screensaver starts and you would like to quickly avoid
desklock, otherwise need to stop talking, unlock and continue).
