In the case where one wants to answer a question using a number of propositions and lemmas with proofs, I think one can organize it better with this feature on Wikipedia for hiding proofs. The link shows how the proof of the integrability condition is hidden thus giving the section a sense of better organization with the show, hide buttons.
I think it will be a useful feature on MSE as one can
- Organize one's answer/question better.
- Make long responses appear shorter.
Other users may find other advantages of this feature but this is all I can think of.
