Some ideas for courses

Hi,

so far I love FluentCommunity. In large courses with many lessons, more structure would help to maintain an overview. Here are a few ideas for improvement:

• Deeper structure. Let's have modules -> topics -> lessions. At course overview I only want to see modules, inside a module I want to see lessions structured in topics.
• Right side navigation: I want to see lessions/topics of the viewed module only.
• Images for modules. For modern course view I want to add images to my modules.
