This package can help you format your notes easily and give them a unique front page for every chapter and section. It calculates your progress and then displays the progress bar under the title. It also displays a partial table of contents under every progress bar and only shows the sub-directories of the current part. To generate this, you can simply enter your current completed titles with a command that accepts variable arguments. Still, that also helps reviewing notes. You can also configure the color of the bar.

This package provides seven predefined chapter heading styles. Each style can be modified using a set of simple commands. Optionally one can modify the formatting routines in order to create additional chapter headings.

This package provides the \ECG command, which draws electrocardiograms (ECG). It can generate different types of wave.

This package provides commands to give an easy way to control the size and blackness of delimiters: append 1-4 bs to command for larger sizes; prepend B for for boldface. These commands reduce the likelihood of incomplete delimiter pairs and typically use fewer characters than the LaTeX default.

These packages are either mandated by the core LaTeX team, or very widely used and strongly recommended in practice.

This package provides macros and an environment for creating Sankey diagrams, i.e., flow diagrams in which the width of the arrows is proportional to the flow rate.

This package provides environments and commands for pairing lines, bottom lines, and tagged lines, intended to be used in particular for word-by-word glosses, translations, and bibliographic attributions, respectively.

This is a simple TSV (tab-separated values) reader for LuaLaTeX and plain LuaTeX. It also supports (non-quoted) comma-separated values, or indeed values separated by any character.

This package offers LuaLaTeX and XeLaTeX support for the Libertinus OpenType fonts. Missing fonts are defined via several font feature settings. The Libertinus fonts are similar to Libertine and Biolinum, but come with math symbols.

This package allows you to create and print scrambled environments for purposes such as randomized hint environments. You can mark a location with a series of hints, and then print the hints at the end in a pseudo-random order. The general structure follows: there is an outer environment which creates the label, an inner environment that creates the references, and a print command that prints out all of the hints. This generalizes beyond hints; one can create scrambled solutions as well, etc.

Nath is a LaTeX style to separate presentation and content in mathematical typography. The style delivers a particular context-dependent presentation on the basis of a rather coarse context-independent notation. Highlighted features: depending on the context, the command \frac produces either built-up or case or solidus fractions, with parentheses added whenever required for preservation of the mathematical meaning; delimiters adapt their size to the material enclosed, rendering \left and \right almost obsolete.

This package defines macros for third-person singular pronouns (\E, \Em, \Eir, \Eirs), which expand differently according to a masculine/feminine switch. (If the switch is masculine, they would expand to he, him, his and his; if feminine, they would expand to she, her, her and hers. Apart from the pronouns, one can define word pairs, such as mother/father, daughter/son, and so on. Gender may be defined once per document, as an environment, or may be flipped on the fly.

This package provides support for Tibetan using Omega.

dvicopy is a utility program that allows one to take a DVI file that references composite fonts (VF) and convert it into a DVI file that does not contain such references. It also serves as a basis for writing DVI drivers (much like DVItype).

This package provides support for interactive computing sessions with e-TeX (or pdfTeX) executed on the command line. Once xintsession is loaded, e-TeX becomes an interactive computing software capable of executing arbitrary precision calculations, or exact calculations with arbitrarily big fractions. It can also manipulate polynomials as algebraic entities. Numerical variables and functions can be defined during the session, and each evaluation result is stored in automatically labeled variables. A file is automatically created storing inputs and outputs.

Miama Nueva is a handwriting and script font with over 1300 glyphs that supports Latin, Cyrillic, and Greek. It comes complete with LaTeX support.

This package provides some commands (in English and in French) to work with a Scrabble board.

GFS Artemisia is a relatively modern font, designed as a general purpose font in the same sense as Times is nowadays treated. The font supports the Greek and Latin alphabets. LaTeX support is provided, using the OT1, T1 and LGR encodings.

This package can assign equation numbers to inline equations. When Japanese is supported, you can switch to circled equation numbers.

This highly experimental package can be used to add NFSS-declarations of combo fonts to LuaLaTeX documents.

This package provides MetaPost tools for drawing simple probability trees. One command and several parameters to control the output are provided.

This package provides sans-serif Greek fonts to match the URW Bookman set (which are distributed with Kerkis). The Kerkis font set has some support for mathematics as well as other glyphs missing from the base URW Bookman fonts. Macros are provided to use the fonts in OT1, T1 (only NG/ng glyphs missing) and LGR encodings, as well as in mathematics; small caps and old-style number glyphs are also available.

This package provides fonts (as Metafont source) for Old English, Indic languages in Roman transliteration and Puget Salish (Lushootseed) and other Native American languages.

The package (which runs under XeLaTeX) lets you bind fonts to specific Unicode blocks, for automatic font tagging of multilingual text.
