Passei a gostar muito do framedpacote de Donald Arseneau. No entanto, há alguns ajustes que gostaria de adicionar, mas não sei como.
Seja para mesclar os dois ambientes framede shaded, ou modificar um e deixar o outro, ou criar um terceiro ambiente todos juntos chamado boxor boxednão está claro, mas estou inclinado para o último.
Adoro shadedcomo está, com a opção de sangrar na margem ou adicionar uma estrela, empurrando o ambiente para se alinhar com a margem. Isso é ótimo como está. Mas não tem a opção de ser enquadrado. E o framedambiente também não tem opção de sombreamento, nem tem opção de ultrapassar a margem como shadedfaz.
A idéia principal é provavelmente criar um ambiente totalmente novo chamado boxedque seja praticamente um shadedambiente que sangra na margem, mas com a opção de criar uma borda ao redor dele. E então um boxed*ambiente correspondente que se alinha com a margem como shaded*.
Além disso, seria muito útil ter algum controle sobre essas bordas: Opções como topframe, leftframe, rightframe, e bottomframe, bem como framecolor(e shadecolor) me permitiriam criar um quadro muito mais interessante em contraste com o próprio framedambiente do pacote. E talvez um parâmetro de pacote \usepackage[booktabs]{boxed}defina, por padrão, esses valores para corresponder às espessuras das linhas das booktabstabelas (para que você não precise defini-los sempre que quiser usar esse ambiente).
E só para fazer issorealmenteinteressante, definir um raio para os cantos topleft, topright, bottomlefte bottomrightindividualmente, e possivelmente até mesmo adicionar uma sombra sofisticada abaixo, poderia completar a aparência e a controlabilidade deste ambiente.
(Editar: e possivelmente uma opção para redefinir a largura da caixa manualmente? Por padrão, sangre na margem ou alinhe com o *. Então, se você fornecer um textwidthna não- *caixa, a caixa terá essa largura mais a largura extra de o preenchimento; se você fizesse o mesmo em um *ambiente ed, a caixa teria a largura de textwidth, mas não calcularia a largura extra do preenchimento.)
Por outro lado, não: se você escolheu escrever um cabeçalho personalizado com direitos autorais como Donald Arseneau fez, considere adicionar a mim e a você mesmo, já que você escreveu o código e eu tive a ideia, e talvez mencione Donald Arseneau por fornecer a Fundação.
Por outro lado: setodas essas opções já estão disponíveis em outro pacote, forneça um nome de pacote e um exemplo de ambiente in a box comtodas essas opções em uso, para não mencionaruma solução para as espessuras de borda padrão definidas para corresponder às bordas das tabelas booktabs.

% framed.sty
% ~~~~~~~~~~
% Create framed, shaded, or differently highlighted regions that can
% break across pages. The environments defined are
% framed - ordinary frame box (\fbox) with edge at margin
% oframed - framed with open top/bottom at page breaks
% shaded - shaded background (\colorbox) bleeding into margin
% shaded* - shaded background (\colorbox) with edge at margin
% snugshade - shaded with tight fit around text (esp. in lists)
% snugshade* - like snugshade with shading edge at margin
% leftbar - thick vertical line in left margin
%
% to be used like
% \begin{framed}
% copious text
% \end{framed}
%
% But the more general purpose of this package is to facilitate the
% definition of new environments that take multi-line material,
% wrap it with some non-breakable formatting (some kind of box or
% decoration) and allow page breaks in the material. Such environments
% are defined to declare (or use) \FrameCommand for applying the boxy
% decoration, and \MakeFramed{settings} ... \endMakeFramed wrapped
% around the main text argument (environment body).
%
% The "framed" environment uses "\fbox", by default, as its "\FrameCommand"
% with the additional settings "\fboxrule=\FrameRule" and "\fboxsep=\FrameSep".
% You can change these lengths (using "\setlength") and you can change
% the definition of "\FrameCommand" to use much fancier boxes.
%
% In fact, the "shaded" environment just redefines \FrameCommand to be
% "\colorbox{shadecolor}" (and you have to define the color `"shadecolor"':
% "\definecolor{shadecolor}...").
%
% Although the intention is for other packages to define the varieties
% of decoration, a command "\OpenFbox" is defined for frames with open
% tops or bottoms, and used for the "oframed" environment. This facility
% is based on a more complex and capable command "\CustomFBox" which can
% be used for a wider range of frame styles. One such style of a title-bar
% frame with continuation marks is provided as an example. It is used by
% the "titled-frame" environment. To make use of "titled-frame" in your
% document, or the "\TitleBarFrame" command in your own environment
% definitions, you must define the colors TFFrameColor (for the frame)
% and a contrasting TFTitleColor (for the title text).
%
% A page break is allowed, and even encouraged, before the framed
% environment. If you want to attach some text (a box title) to the
% frame, then the text should be inserted by \FrameCommand so it cannot
% be separated from the body.
%
% The contents of the framed regions are restricted:
% Floats, footnotes, marginpars and head-line entries will be lost.
% (Some of these may be handled in a later version.)
% This package will not work with the page breaking of multicol.sty,
% or other systems that perform column-balancing.
%
% The MakeFramed environment does the work. Its `settings' argument
% should contain any adjustments to the text width (via a setting of
% "\hsize"). Here, the parameter "\width" gives the measured extra width
% added by the frame, so a common setting is "\advance\hsize-\width"
% which reduces the width of the text just enough that the outer edge
% of the frame aligns with the margins. The `settings' should also
% include a `restore' command -- "\@parboxrestore" or "\FrameRestore"
% or something similar; for instance, the snugshade environment uses
% settings to eliminate list indents and vertical space, but uses
% "\hspace" in "\FrameCommand" to reproduce the list margin ouside the
% shading.
%
% There are actually four variants of "\FrameCommand" to allow different
% formatting for each part of an environment broken over pages. Unbroken
% text is adorned by "\FrameCommand", whereas split text first uses
% "\FirstFrameCommand", possibly followed by "\MidFrameCommand", and
% finishing with "\LastFrameCommand". The default definitions for
% these three just invokes "\FrameCommand", so that all portions are
% framed the same way. See the oframe environment for use of distinct
% First/Mid/Last frames.
%
% Expert commands:
% \MakeFramed, \endMakeFramed: the "MakeFramed" environment
% \FrameCommand: command to draw the frame around its argument
% \FirstFrameCommand: the frame for the first part of a split environment
% \LastFrameCommand: for the last portion
% \MidFrameCommand: for any intermediate segments
% \FrameRestore: restore some text settings, but fewer than \@parboxrestore
% \FrameRule: length register; \fboxrule for default "framed".
% \FrameSep: length register; \fboxsep for default "framed".
% \FrameHeightAdjust: macro; height of frame above baseline at top of page
% \OuterFrameSep: vertical space before and after the framed env. Defaults to "\topsep"
%
% This is still a `pre-production' version because I can think of many
% features/improvements that should be made. Also, a detailed manual needs
% to be written. Nevertheless, starting with version 0.5 it should be bug-free.
%
% ToDo:
% Test more varieties of list
% Improve and correct documentation
% Propagation of \marks
% Handle footnotes (how??) floats (?) and marginpars.
% Stretchability modification.
% Make inner contents height/depth influence placement.
