I'm probably asking for something very complex, but in my not-expert mind it seems to me that is really weird not to have smart \marginpar (which I really want to use as a way to typeset margin notes) command which allows to have a nice typeset with margin par on the right side of the text for twoside documents (I used the proposed solution given here, the packahe mparhack) and at the same time the possibility of extend marginpar over multiple pages (for which I haven't find a solution yet).
I'm actually using book class, because I discovered too late that memoir class can provide something near what I want, and I would like to keep this class as there are lot of edit I made that seems not to compile with memoir class.
So provided \documentclass[twoside]{book} how can I achieve at the same time a note on the marginpar space which breaks page when it reaches the end of it and stays on the right side of the paper in twoside documents?
I looked a lot around but did not found any solution that fit my case, how can a thing like that so under-developed?
Thanks to all that will answer!
