I do think Lomiri has a symmetry problem mainly because of the left Launcher. And that's more emphasized on smaller or portrait screens like phones compared to desktops. I myself has been thinking of how to improve that
. One of the things I thought is to hide the Launcher when the Drawer is shown. And maybe transition them to like a bottom dock? I think this quite difficult to solve and I'm not really good with designs and art 
Given that you're a graphic designer, maybe you help on this regard and propose a design?
