The administrator has not changed since almost his birth. The community needs to decide which format of the Site Administrator should be taken as a modern basic framework - as the official version of the osCommerce BS, HTML5, PHP-7, supported by the community.
There is another good version of the administration panel available developed by SoloMono. We all have to make a decision together. And based on this, adapt existing modules to the generally accepted format. No need to spray power on many different versions. Let's choose one and develop it together.
We need to combine our strength, knowledge and experience. We need to remember how we started this almost 20 years ago. This will be the reanimation of osCommerce and our common success.
