How to use:
* Load the entire map by moving to the bottom, then click the Regenerate button.
* There's more commands on the right-click menu or by clicking on the extension you used to load the script
* The script only sees the chapters that are currently loaded in the map page. You might have to regenerate after loading more
* There's also a toggler for the map to close/open all chapters of a certain depth
* If you got the map data, the counter will also appear when choosing your next chapter
