I have recently read this article and was wondering whether To-Do Lists also qualify as an Extended Mind?

In Chalmer and Clark's paper at they list the use of pen and paper to perform multiplication as an example of extended cognition, and it seems that the to-do list falls into the same category. Furthermore, from the Wikipedia article

The main criterion that Clark and Chalmers list for classifying the use of external objects during cognitive tasks as a part of an extended cognitive system is that the external objects must function with the same purpose as the internal processes.

and since the purpose of the paper is storage and organization, the same purpose as the internal process, I believe that the answer to your question is "yes".
