% Cleveref automatically handles:
% "Chapter 3" vs "Section 1.2" vs "Figure 4.5"

% Systematic labeling convention
\label{type:chapter:section:subsection}

% Examples:
\label{ch:intro}                    % Chapter
\label{sec:intro:background}        % Section
\label{subsec:intro:background:history} % Subsection

\label{thm:theory:main}            % Theorem
\label{def:terms:important}         % Definition

% Easy to find and maintain
% Avoids naming conflicts
% Self-documenting

% Create a references file
% refs/labels.tex
\newcommand{\introduction}{\cref{ch:intro}}
\newcommand{\methodology}{\cref{ch:methodology}}
\newcommand{\maintheorem}{\cref{thm:main}}
\newcommand{\resultsfigure}{\cref{fig:results:main}}

% Use semantic references
As shown in \resultsfigure, our method outperforms...
The proof follows from \maintheorem...

% Benefits:
% - Central management
% - Easy to update
% - Semantic naming
% - Find/replace friendly

% Check for undefined references
\usepackage{refcheck}

% Shows unused labels
\usepackage{showlabels}

% During development only:
\usepackage[notref,notcite]{showkeys}

% Custom warning for missing refs
\makeatletter
\def\@refundefined#1{%
  \textbf{[REF: #1??]}%
  \@latex@warning{Reference `#1' undefined}%
}
\makeatother

% Fast draft compilation
\documentclass[draft]{book}
% Images shown as boxes
% Overfull boxes marked
% Much faster compilation

% Conditional draft mode
\usepackage{ifdraft}
\ifdraft{
  \usepackage[disable]{todonotes}
  \overfullrule=5pt
}{
  \usepackage{todonotes}
  \overfullrule=0pt

% Skip expensive operations
\ifdraft{
  \renewcommand{\includegraphics}[2][]{%
    \fbox{#2}% Just show filename
  }
}{}

% Externalize TikZ pictures
\usepackage{tikz}
\usetikzlibrary{external}
\tikzexternalize[prefix=tikz/]

% Compile once, reuse many times

  % Complex diagram
  % Only recompiled if changed
\end{tikzpicture}

% Externalize other content
\usepackage{standalone}
\usepackage{docmute}

% In main.tex:
