I can’t offer any advice on using the tutor-riche plugin. But, have you considered using theming to modify the landing page?
- Changing the appearance of Open edX — Tutor documentation
- GitHub - overhangio/tutor-indigo: An elegant, customizable theme for Open edX
We are using a modified version of Indigo on our site to control how users log in. The process is straightforward. Basically, the files you add to the theme override the files in Open edX. I think we just copied the template files from the Open edX code base and then modified it to meet our needs.
You could copy the ‘indigo’ folder to env/build/openedx/themes/ per the Tutor instructions, and then start modifying it in the dev environment to build the landing page. You’ll have to rebuild the images and set the theme when you are ready to use the theme in your production environment.
I hope this helps!
