OPW editor is not very. Especially as LF is handled.

I think you're basically asking for line breaks to be line breaks, and not full paragraph breaks?

I personally would prefer that because it's poetry-friendly.
Also, sometimes a line break in the editor is non-existent in the published post. Especially double breaks.
Is this happening with copy and paste? I saw that today.
That is the time I noticed it. When I went back in and edited it I got more breaks than from the paste, but I was still unable to get a double break.
