+If there are footnotes (or any other type of inline \tex{insert}) present in the moved line, \lwc/ will move both the \q{footnote mark} and the \q{footnote text} such that both are on the same page. However, this may lead to an odd blank space at the bottom of the page since \lwc/ needs to move both the line and its footnotes. Footnotes cause the same page-breaking issues in unmodified Plain~\TeX{} and \LaTeX{}, so this is mostly unavoidable.

The documented interfaces of \lwc/ can be considered stable: I'm not planning on removing or modifying any existing options or commands in any way that would break documents.
-However, \lwc/'s page breaking \emph{is} subject to change. I will attempt to keep page breaks the same wherever reasonable; however, I will rarely make modifications to the algorithm when I can improve the output quality.

+From here and until the end of this manual is the raw source code of \lwc/. This is primarily of interest to developers; most users need not read further.

+This code vaguely resembles the typical \LaTeX{} literate programming style, although I use extensive inline comments instead of arcane \sans{docstrip} macros. Hopefully this is useful as a reference for advanced \lwc/ users as well as anyone doing extensive node manipulation in \LuaTeX{}.
