The web app I am now working on as a pilot project for my learning has a very complex settings page. It has 18-20 main categories and tweaks about 200 configurations within these categories. There are 2 access levels, one is a manager and another is owner. Owner can see all changes, but doesn't necessarily have to configure all of them. Manager can see only select tweaking options and has to configure things by himself.
Right now I am using a vertical tabbed approach. How can I improve it further?
