The exercises in the completed-components directory each contain the solution for future exercises. This makes it very difficult to catch up and/or only complete one lesson. If I want to just do the live region exercise, I have no way of starting from the end of exercise 3, if I want to just do the focus management section, I have no way of starting from the end of exercise 4, etc.
Do you have the completed solution code for each exercise? If so can the completed-components sub-directories be updated accordingly?
