This package is an extension of the keyval package and offers additional macros for setting keys and declaring and setting class or package options. The package allows the programmer to specify a prefix to the name of the macros it defines for keys, and to define families of key definitions; these all help use in documents where several packages define their own sets of keys.

The package can generate thumb indexes for your document. It features printing thumb indexes on one- or two-sided pages, along with background- and foreground-color selection and full LaTeX styling of the chapter numbers in the thumb indexes. The height of each thumb index is automatically chosen based on the number of chapters in your document, while the width is chosen by the user. The package is designed to work with the memoir class, and also requires PerlTeX and TikZ.

This package defines web-safe colors for use with color package. It is intended for both authors and package writers (e.g., to create Beamer color themes).

This package generates alphabet soup puzzles (aka word search puzzles), and variations using numbers or other symbols. It provides macros to generate an alphabet soup style puzzle (also known as word search puzzles or find-the-word puzzles). It also allows creating number soup and soups with custom symbol sets.

This package provides formatting for footnotes in long legal documents, using hanging indents to make them look nicer.

The longfigure package uses and relabels components of the well-known longtable package to provide a table-like environment that can display a stream of figures as a single figure that can break across pages.

Latin Modern Math is a maths companion for the Latin Modern family of fonts, in OpenType format. For use with LuaLaTeX or XeLaTeX, support is available from the unicode-math package.

This package provides helpful commands to work with the FO[.] language in LaTeX including syntax highlighting in listings.

This package provides a mechanism to control the space after commas and semicolons in mathematical expressions.

This package collects together examples that have been posted to the PSTricks mailing list, together with many additional features for the basic pstricks, pst-plot and pst-node, including: bugfixes; new options for the pspicture environment; arrows; braces as node connection/linestyle; extended axes for plots (e.g., logarithm axes); polar plots; plotting tangent lines of curves or functions; solving and printing differential equations; box plots; matrix plots; and pie charts.

The Tango color palette defines some color names and their RGB codes. This LaTeX macro package implements these color names, so one can easily access these colors by their names.

This package provides a package which provides access to some interesting characters of the Text Companion fonts (TS1 encoding) in maths mode.

Starting with TeX Live 2010, the various formats, that directly generate PDF, default to generating PDF 1.5. This is generally a good thing, but it can lead to compatibility issues with some older PDF viewers. This package changes the version of PDF generated with formats (based on pdfTeX or LuaTeX in PDF mode), back to 1.4 for documents that need to achieve maximal compatibility with old viewers.

This package provides a flexible LaTeX2e class for typesetting school cafeteria menus consisting of two lunches (with dessert), and dinner. It supports two different layouts. The first layout is optimized for printing the menu on A4 paper. The second layout is optimized for smartphone screens and uses one (A6 sized) page per day. Supported localizations are English (GB/US) and German.

The terminalcode package provides authentic terminal-style code display environments for LaTeX documents. It features UTF-8 box-drawing characters, comprehensive ANSI 16-color support with dynamic dark and light themes, and seamless integration with external code files.

The package provides a versatile way to stack objects vertically in a variety of customizable ways. A number of useful macros are provided, all of which make use of the stackengine core.

This package defines two commands (and aliases) aimed at implementing a constant time switch/case alike command.

This package is meant for setting parameters in a LuaLaTeX document in a more programmatic way with YAML. Parameters can be specified by adding a ``recipe'' file. These recipe files describe the parameter's type, placeholders or default values. From thereon, the placeholders can be displayed in the document and an ``example'' document can be created. An ``actual copy'' document can be created by loading additional ``payload'' files, which all must correspond to a recipe file.

This small package provides a convenient input syntax for boxes that don't break their text over lines automatically, but do allow manual line breaks. The boxes shrink to the natural width of the longest line they contain.

mkpic provides an easy interface for making small pictures with mfpic. To this end you create an input file consisting of commands, one per line, with space separated parameters (or you modify the DATA section of the mkpic script, which is used if you run it without an input file).

autotype is a LuaLaTeX package for automatic language-specific typography. Currently, it supports ligature suppression at word boundaries, long s insertion for blackletter typesetting, and weighted hyphenation, but only for German (old and new orthography).

The package provides a maths support that amounts to modifications of the STIX sans serif Roman and Greek letters with most symbols taken from newtxmath.

This package provides a command that generates a list of warnings that are printed out at the very end of the logfile. This is useful for warnings such as ``Rerun for this or that reason'' or ``This is a draft''.

This package recreates some AmongUs characters in TikZ environments. Some interesting uses alongside other packages are also supported.
