If you use fancy page-style you can use LaTeX-commands for what is
displayed in header (left, center, right) and footer (left, center,
right). And if a line is displayed or not. Because Lyx is for those
people who are no specialists for LaTeX it would be excellent, if
after activation of fancy page-style in the document-settings there
would be chechboxes for check/uncheck the lines and fields for all 6
positions where you can type your own text or choose "variables" like
page-number, date, section-title,... And when you use 2-page-layout
this shoule be automatically mirrored for the opposite pages. A GUI
for this often needed and by many beginners often wanted feature would
be a great step forward.
