Last month, lesson organization made it to the top of our feature-request list. Today, with the introduction of Tags, I am happy to say that your biggest problem is solved.
Now, admins can create and manage tags via the Tag tab within the cog icon.

From there, you can dive into any lesson or course to apply one or more tags.
Once you are ready, just head back to your list of lessons or courses, and use the Filter do find what you need, without hassle.
Let us know your thoughts! And, as always, send firstname.lastname@example.org a note about any features you’d like us to add in the future.
