This feature already exists, but you control whether or not it's enabled. See the doc for exercise skipping here for how to turn it on / off:

It seems like a very bad idea to make the above ambiguity possible--but that said, the problem remains and this issue should be reopened.

If an author does not want to let their students skip exercises and also has a sub-section without an exercise, the sub-sections beyond it will remain hidden and inaccessible:

---
title: "Demo Tutorial"
output: 
  tutor::tutorial:
    progressive: true
runtime: shiny_prerendered
---

```{r setup, include=FALSE}
library(tutor)
```

## Welcome

### Visible sub-section

This sub-section is visible. But it does not have an. Notice that there is no "Next Topic" button.

### Hidden sub-section

This sub-section is hidden. You do not know that it exists.

## Second Task

Once "finished" above, you can navigate here with the TOC.

If the author does allow skipping. The hidden sub-sections will be cued with a button that says "Skip" (it should say "Go On"). And this button does not reveal the section when students click on it.
