@Robotech_Master,
As your article has gone into detail about manually editing the .conf file so you can take screenshots you may also like to know that you can use a similar edit to remove the header & footer wasted space you also made a point of in your article.
Code:
[FeatureSettings]
FullScreenReading=true
will add an extra checkbox to your
Settings - Reading Settings page so you can henceforth display/remove header/footer at your convenience.
