With fancyhdr, you can define variable headers and footers. All you need is the following template with sample entries, which must be included in the preamble.
As the name suggests, you need xcolor to change the font colour. The following colours can be used: white
black
red
green
blue
cyan
magenta
yellow
gray
darkgray
lightgray
brown
lime
olive
orange
pink
purple
teal
violet. The following code is required for this.
\textcolor{COLOR}{Text}
enumitem
With enumitem, you can vary and/or format bullet points.
% itemize
% Any symbols can be used here.
\begin{itemize}[label=!]
\item First item
\end{itemize}
% enumerate
% Here, you can start with any number.
\begin{enumerate}[start=4]
\item Fourth item
\end{enumerate}
% Here, the numbers can be formatted as desired.
\begin{enumerate}[label=\textbf{\arabic*.}]
\item Thick item
\end{enumerate}
% Text can also be placed here.
\begin{enumerate}[label=\textbf{Aufgabe \arabic*:}]
\item Thick Item
\end{enumerate}
% Here, the numbers are Roman (small).
\begin{enumerate}[label=(\roman*)]
\item Roman item
\end{enumerate}
% Here, the numbers are Roman (capital).
\begin{enumerate}[label=\Roman*]
\item ROMAN item
\end{enumerate}
hyperref
With hyperref, references to other chapters, pages, images, etc. can be created.
\section{Section}
\label{sec:section} % important
A marked equation:
\begin{equation}
E = mc^2
\label{eq:demo} % important
\end{equation}
\section{List with hyperlinks}
\begin{enumerate}[label=\arabic*.]
\item Link to section \ref{sec:section}
\item Link to equation \ref{eq:demo}
\item External link: \href{https://google.ch}{Google}
\item External link with visible URL: \url{https://www.wikipedia.org}
\end{enumerate}
float
With float, you can basically have floating environments placed automatically. This change only affects the first line of the floating environments. Here is an example using figures:
\begin{figure}[H] % The H now ensures the optimal placement of the sliding environment.
titlepage
Using titlepage, you can create custom title pages with images, for example, which is not possible with the normal \maketitle command. Below is a sample title page for an academic paper:
\begin{titlepage}
\centering
\vspace*{1cm}
\includegraphics[width=1\textwidth]{example-image}
\vfill
{\LARGE \textbf{Title} \\ Subtitle}\\[0.5cm]
\vfill
\begin{center}
{\large
\textbf{Author:} John Doe \\ [0.3cm]
\textbf{Type of work:} investigation \\ [0.3cm]
\textbf{Instutition:} Bündner Kantonsschule Chur, Gymnasium}
\end{center}
\end{titlepage}
