Nice. Love the quick setup. Glitches seen have been minimal. I really don't know how you do it, given all the possible combinations of hardware & browsers. Still working through the setup instructions but a few hiccups that I noticed below:

Catalog Category Buttons which are functional @ max desktop width are non-functional as shown in the screenprint below. I had expected the non-functional button to yield the same result as the teeny down arrow.

Alignment of DETAILS button on product pages a tad off.

Custom Left Slide out works on desktop but not functional on landscape tablet (Samsung 8" Galaxy Tab3). Can the double-arrow button be turned off, disabled or removed? It does disappear on Portrait tablet, probably as designed.

Down for Maintenance notification bar has an effect on alignment.
