I notice that the forum software has become very proactive in preventing vertical spacing. For example, it will not let me open a new section after giving a code example:
here's some code
This is an entirely different section and ideally I would want to have at least two empty lines between it and the preceding text. Like I can when it's text sections only (see immediately below).
The other thing is that if I mistakenly put two or more consecutive spaces in the text, they are not merged into one. IMHO, these two behaviors should be reversed.
