Hello, I'm using the tufte layout documentclass with the options justified und marginals=raggedright. This should justify the text, but not the sidenotes and marginnotes. But LyX produces justfied marginnotes and justified sidenotes too. I exported the text to normal Latex an compiled it with another program. It worked fine now, but it should not be not the aim of LyX.
If I use LyX to write marginnotes it always uses \marginpar. There is no option for \marginnote or \sidenote. Therfore on has to use ERT. Even LyX supports the marginfloat environment the offset option is not supported. Again one has to use ERT. Karl
