UPDATE (only for Opencart 2.3... versions) - in new version extension has translate file and does not change any native files !
It's free extension for Opencart, it will add opportunity to edit main product properties from the product list page.
The module is installed by OCMODE installer and replace product list view file. That's means after deleting extension, product list will stay changed (only old versions). Therefore you must save reserve copy of this file before installing.
All changes of product saved via AJAX, without refreshing page.

IT'S TESTED ON 2.3.0.2 and 3.0.2 versions ONLY, but it must compatible and with others versions of OPENCART 2 (only old version - it will change original template file, therefore you must make a reserve copy)
