#ynh-overlay-switch need to be removed from printing

#1

i agree that is kinda handy to switch between apps but when it comes to printing that is annoying

consider adding a new css file media="print"

then

#ynh-overlay-switch
{
    display: none;
}
#2

Something like that is possible normally :

@media print {
   #ynh-overlay-switch
   {
    display: none;
   }
}

or with a new file print.css :

@import url("print.css") print;

print.css :

#ynh-overlay-switch
{
  display: none;
}
