How do you get to the store cart in the mobile layout? I can't see it anywhere.

It would be nice to have an indication when you have something in the cart:

And then a button to go to the cart when you open the menu:

 

Or maybe just place a cart icon with the link next to the menu button if you have something in it.

 

If this is not a bug, I will look into creating a plugin.

Plugin is ready, waiting to get approved.
