How do I add/remove slide group headers? Shown in picture as Warm-Up, Activity 1, Cool-Down, etc. I cannot find anywhere in the activity builder to change this feature. Thanks!
You can edit them using the title on the slide or the </> button next to teacher tips. It depends on where the information was input.
I think these are a hidden feature that only Desmos and certain other activity creators have access to. Unless something has changed, I don’t think these can be created or edited by regular users.
I am wondering if this is still the case… Give the public access to the screen headers! Please and thank you 
Currently still an internal feature for the curriculum, which you’ll see escaping when someone uses a curriculum activity/screen as a base.
