Oh my! Seems like you might soon, finally, be able to create chapters for your podcast directly in Audacity!
For years you've been able to add a file along with the audio in your podcast, which indicates chapters that people can jump between. Still, AFAIK, you still have to use a separate app just to create this, when it should be trivial in any audio editor!
In 2024 I asked #Audacity to implement this, and now it's marked as ready to merge! Yey! https://github.com/audacity/audacity/issues/7078
