Change default behaviour of enter to a new paragraph (new line, but with no margins). A user can press enter twice to create space between elements.

When you type enter in the rich text editor, a paragraph is created – this should be a line break, two of which in succession should produce a paragraph.

In a table, the paragraph is converted to a break, which is inconsistent.

Multiple empty paragraphs should become escaped newlines (
), but don't.

Most people don't know they can press SHIFT+ENTER to achieve this effect in the RTE. It's not discoverable.
