Pressing Enter or Shift+Enter often doesn't work correctly in the Editor.
Pressing Enter after the last 'asdf' text doesn't take you to a new line, it just brings up the '+' button or every once in a while it just does nothing.
Pressing Shift+Enter after the last 'asdf' text often doesn't take you to a new line either, it just adds a line above 'asdf' yet keeps the cursor at the end of 'asdf'.
I've tried going in and out of the Editor, and many times it doesn't work. The client is having issues with it too.
