First of all, love this theme!! It's simplicity, focus on content is superb and the responsive layout is beautiful.
However, when I tested it on my iPad, the menu went wonky. I could open the folder on top but not close it, it closed when I clicked on the pin. (neither does it close on android smartphone or in Safari on iPad)
When I clicked on the menu, the menu content slide opened and closed a few times (flickering), but I could not select anything, because it did not stay open.
I have tested Editor on your demo site in Chrome on the iPad. It works in Safari.
Do you have a fix for this problem?
