Re: How to add a new sidebox from scratch?
Am I even in the right ballpark?
Also, what actually makes the file appear in the sidebox controller so it can be turned on and controlled in the admin?
You're hitting a home run.
The sideboxes are auto-magic and as long as you have the right files in the right places, The Zen Cart Admin will find them.
