I just submitted v1.0.8 to the Plugins for review; the released versions always available at the plugin's GitHub repository or on my website.

This version of the plugin corrects the following issues (based on GitHub issue number):

#51: Really correct handling for Stripe payment method
#53: Can't checkout if "free shipping over" is set within the ot_shipping module
#55: Don't render sections of the checkout_one page, depending on shipping-/payment-module availability.
#56: Correct interaction with stores using MooTools-based scripts

NOTE: The plugin's base template for the checkout_one page has changed; make sure to update any template-override version you might have created!
