Finally there is the option to create a private mode (yay) where participants see illegible scribbles instead of text. I would like an improvement on this feature by having the option to hide the entire sticky note,shapes, or anything else that gets added while the private mode is in session. Private mode could be way more versatile for different work cases then is currently possible.
I.e. In my case I like to use stickies to create a simple rating system akin to the example here where the colour of a sticky indicates the level/rating.
Currently I have no way to have a private session where I want to hide and reveal simultaneously, anything else other than text.
