No, I'm not talking about a rabbit hole like the one in Alice in Wonderland. There are many definitions of "rabbit hole" when it comes to the online world (most of which are not helpful in the online course environment). In this case, I'm talking about a seemingly endless number of clicks to get to the thing you want.
While it is very important to maintain organization in your online course, and folders are a great way to do that, you always need to keep in mind how many folders you are asking a student to open to get to a particular assignment, reading, assessment, etc. It is recommended that it take no more than 3 clicks to get to any specific thing. Due to the nature of ANGEL, I suggest starting your click count after you make it to the Lessons tab. This would allow you 2-3 folder levels, anything past that starts to get excessive. Another thing to remember is if there is only one item that would go in a specific folder, don't put it in a folder (by adding a folder for a single item you are not adding organization, you are only adding a click to get to it).
This idea is definitely one of the easier aspects of online course design but it is also easily forgotten. So please, take a moment to look at your course and make sure you aren't throwing your students down rabbit holes.
