I just tested out this menu and generally I like it and think it would be nice to have on my project. But the moving of the page to the right every time when I open the menu makes me feel dizzy (motion sickness).

Is it intended that the menu moves the whole website to the right? I would have expected an overlay over the page instead.

I used "Theme Sandbox" for the test.

(Additional general info in case other people are reading this and wondering: This menu won't work properly with the "Default Plus" theme.)
