Nested list are not padded correctly
Nested lists have way too much padding above them, and not enough padding bellow. This makes the layout very weird, and a bit difficult to read.
As you can see, the nested list is completely separated from the paragraph above it, which makes it look like the two are completely unrelated (even though they aren't).
On the other hand, the nested list needs more padding bellow, because the block of text bellow, while still part of the same top-level item, is still supposed to be a different paragraph.
