Is this something that one would like as default, ie included by LyX?

Summary description: Automatically remove widows and orphans from any
document
Announcement text:
----------------------------------------------------------------------
Lua-widow-control is a Plain TeX/LaTeX/ConTeXt package that removes
widows and orphans without any user intervention. Using the power
of LuaTeX, it does so without stretching any glue or shortening any
pages. Instead, lua-widow-control automatically lengthens a
paragraph on a page where a widow or orphan would otherwise occur.
Unmodified TeX has very few ways of preventing widows and orphans.
In documents with figures, section headings, and equations, TeX can
stretch the vertical glue between items in order to prevent widows
and orphans, but many documents have no figures or headings. TeX
can also shorten the page by 1 line, but this will give each page a
different length which can make a document look uneven. The typical
solution is to strategically insert \looseness=1, but this requires
manual editing every time that the document is edited.
Lua-widow-control is essentially an automation of the \looseness
method: it uses Lua callbacks to find "stretchy" paragraphs, then it
lengthens them to remove widows and orphans.
Lua-widow-control is compatible with all LuaTeX-based formats. All
that is required is to load the package at the start of your
document.
To load:
- Plain LuaTeX: \input lua-widow-control
- LuaLaTeX: \usepackage{lua-widow-control}
- ConTeXt (LMTX): \usemodule[lua-widow-control]
