It would be nice to add an ability to obfuscate everything on a page except a thing I want to show to somebody (so a receiver can focus on important details and blot out visual noise).

Actually, there is the function that can blur any selected text, and what I'm asking for is the opposite of that—make only a selected text visible. If it also possible, would be cool to see the same functionality for pictures.

Besides that, great add-on, tysm for making it!

I love it, the result is pretty cool. I will use it to share the development of my own projects without giving too much data.
