Customizing PowerStore with other extensions
This is most definitely possible, but not something that will happen overnight.
We are currently working on producing How Tos to assist PowerStore owners with making certain modifications with eCart. We are focused on creating these first as they are in high demand for our customers.
As for our other extensions, we intend to document certain scenarios based on demand and degree of complexity. So, if there is something you are looking for, let us know. We have a contact form for you to submit your documentation ideas: submit-idea.php
Keep in mind that since PowerStore was created using a lot of WebAssist extensions, the documentation for those extensions will still apply when working with PowerStore. The greater an understanding you have of using those extensions, the easier it will be to use them to modify PowerStore.
