hidden most of the time, but always there when you need it
Blindfold aims to blind unneccessary parts of text away from the main screen by putting it in a normally folded section. The text could be toggle up using a button. I intend to use this to hide away ugly mathematic proofs, so this support latex.
Now, installable via the community plugin tab
This is blindfold normally. The buttons "click to reveal.." works as you might think. Click, to reveal.
After clicking, the content is revealed
So that the content which might takes a lot of space, and is not that important could be hidden most of the time, but always there whenever you need it.
In this case, a proof of a theorem is very important, but not insightful, hiding it most of the time makes the document more readable. However, whenever you need to see the proof to prepare for a math exam. It's always just a click.
A blindfold is construct easily by creating a codeblock, like below,
Note that you can you any obsidian function inside this codeblock, ie. 
creates this
