Support over 2 nested paragraph and squashing?

[Lucaffo]

Hi! I love this piece of software. I would ask if it's possible to add a support for over 2 nested paragraph.

Atm you can do:

# Nice Title
## Nice Subtitle
### This is not a sub-subtitle :(

It would be awesome if at least (4 or 5 nested paragraph)

And if i have more than one sub-paragraph it would be awesome and less caothic, if we can squash it clicking on the paragraph.
