I would like to see a hot key added to display a line (purple?) showing the
user's latitude. The line would be similar to the meridian, ecliptic, and
celestial equator lines. The line would intersect the green meridian line and
show the location of the north celestial pole. The intersection would give the
relationship of Polaris to the north celestial pole at the time of display.
This would be helpful in setting up the polar alignment of a telescope.
You seem to have CSS turned off.

After a little more thought, there is a workaround. With the meridian line on
and the azimuthal grid on, zoom into the field of view your telescope has.
Flip the view vertically or horizontally to correspond to your telescope's
view. Center over your latitude's intersection with the meridian and take a
screen shot (best with colors inverted). Print the screen shot and draw your
latitude line on the printout. The result should be the point where you want
to center your equatorial mount's right ascension axis. This method should do
everything the line display would have done.
An even better way to get your latitude's relationship to Polaris is to turn
on the meridian and the equatorial grid. Center the 90 degree point which is
the celestial pole. Now the position of Polaris with respect to the pole at
the Stellarium time is displayed. Zooming in to the field of view you are
seeing through your polar finder telescope gives a good picture of where
Polaris lies with respect to the pole. The view can be inverted vertically or
horizontally or both to agree with your polar finder telescope. Stellarium
time can be set to agree with your time. Jason Dale's Polar Finder program
gives a similar view. Compare what you see with Polar Finder with the above
Stellarium display with your view through your polar finder telescope. This
should give you the information needed to locate Polaris in your polar finder
telescope for a precise polar alignment.
