We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
#124 - Support for reversing sales from the payment gateway's end
This one seems important, but practically a refund scenario is rare, and there's no guarantee every eCommerce hook would be able to do a reversal (depending on exactly what it is doing).
So currently we are just documenting clearly in the new version of the eCommerce tutorial what to do to do a reversal.
If implemented it should work well with the sales log. Deleting a sale would provide a checkbox to also reverse the purchase, or a message if it is not possible for a particular product.

It would be a nice feature though.
