Suggestion: Add total number of exercises after exercise number

[petzi53]

Thank you for your excellent tutorials. As a former professor for continuing education, I enjoy them. I am not a data science expert, but I have some intermediate knowledge of R, Quarto, Git/GitHub. I use your tutorials for a switch from Quarto to Positron.

I have a suggestion to improve the learning experience for people like me:

Currently, learners do not know how many exercises a chapter has. The progress bar in the {learnr} package only works for the main chapters, but not for subsections within chapters. My suggestion is to add the total number of exercises to go after the exercise number. For instance: Exercise 1 of 13 or Exercise 5/13 or a similar hint on how many exercises there are in the current chapter.

At the moment, I have to look through your GitHub source code to get an idea of how much time I will need for the next chapter. Knowing the approximate timeframe is – at least for me – essential for planning and setting aside enough time to work on your tutorials.

That is a great suggestion! I will first need to implement the tools for automating that numbering in the tutorial.helpers package.
