You can edit the heading, time per topic and the topics themselves. If you have any topics in script.js those will be auto loaded into the form and then, when you submit, will be saved to localStorage. They’re only saved to your browser, nowhere else.
If you’d like to change the defaults, you can remix this on Glitch! Scroll down and click on the fish at the bottom, then click remix and you’ll get a new project set up for you which you can edit to your heart’s desire. 😊
