Whereas the data a Lectora.awt is based upon, has this option. I managed to create scripts that auto-generate a Responsive ( 4 views ) .awt based upon a PSD that give the user/designer the option to either keep original Lectora scaling or use a custom scaling percentage. The .awt it generates is fine. At the moment working on a preview option for the designer so he sees how it will end up.
A early version i showed on Luc2016. Then it was limited to 1 page. Now my toolset autocreates a complete fully responsive course from a PSD.
