A: When Fable records the demo of the software/ application - it captures all the html/ css elements of the application.

With on screen html customization - you’ll be able to hide/ edit/ blur/ delete any element on the screen. These can be text elements, images, icons, etc.

Eg: let us a say I recorded a demo of google calendar using fable with my calendar account. With on screen html customization - I change the name from Vikas to XYZ, replace my profile photo with anything else, blur/ hide any calendar events that I don’t want to show, etc.

Hope this helps in understanding!
