Hello.
For managing product reviews, you might find this section of the AbanteCart documentation helpful:
https://abantecart.atlassian.net/wiki/spaces/AD/pages/9994245/Products+ReviewsIt covers how to approve, manage, and display reviews.
Regarding transactions, these are a core part of most eCommerce systems, as they provide a record of customer account activities like refunds, manual adjustments, or loyalty credits.
That said, if you’d prefer not to show the transactions section on the customer dashboard, it is possible to hide or modify elements like that by editing the storefront code.
