I have just upgraded to v4.0 and I see that we no longer have to use the Wiki Markup, very good except for the one thing that I used it for most.
When editing, the Standard editor anoyingly puts in double spacing every time you hit return to go to the next line, so I used to go to the Wiki editor and take out all these extra lines.
How do I do it now, or set the default line spacing at single space instead of double space?
