Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

A software feature is "a prominent or distinctive user-visible aspect, quality, or characteristic of a software system or systems", as defined by Kang et al.[1] At the implementation level, "it is a structure that extends and modifies the structure of a given software in order to satisfy a stakeholder’s requirement, to implement and encapsulate a design decision, and to offer a configuration option", as defined by Apel et al.[2]
The term feature means the same for software as it does for any kind of system. For example, the British Royal Navy's HMS Dreadnought (1906) was considered an important milestone in naval technology because of its advanced features that did not exist in pre-dreadnought battleships.[3]
Feature also applies to computer hardware. In the early history of computers, devices such as Digital Equipment Corporation's PDP-7 minicomputer (created in 1964) was noted for having a wealth of features, such as being the first version of the PDP minicomputer series to use wire wrap, as well as being the first to use the proprietary DEC Flip-Chip module which was invented in the same year.[4][5]
Feature also applies to concepts such as a programming language. The Python programming language is well-known for its feature of using whitespace characters (spaces and tabs) instead of curly braces to indicate different blocks of code.[6]
Another similar high-level, object oriented programming language, Ruby, is noteworthy for using the symbols "@" and "$" to highlight different variable scopes, which the developers claim improves code readability. Its developers also claim that one of its important features is a high amount of flexibility.[7]
The Institute of Electrical and Electronics Engineers (IEEE) defines feature in the (obsolete) standard for software test documentation IEEE 829 as a "distinguishing characteristic of a software item (e.g., performance, portability, or functionality)".[8]
Although feature is typically used for a positive aspect of a software system, a software bug is also a feature but with negative value.
The terminal emulator xterm has many notable features, including compatibility with the X Window System, the ability to emulate a VT220 and VT320[9] terminal with ANSI color, and the ability to input escape sequences using a computer mouse or other similar device, and the ability to run on multiple different Unix-like operating systems (e.g. Linux, AIX, BSD, and HP-UX).[10]
Feature-rich describes a software system as having many options and capabilities.
One mechanism for introducing feature-rich software to the user is the concept of progressive disclosure, a technique where features are introduced gradually as they become required, to reduce the potential confusion caused by displaying a wealth of features at once.[11]
Sometimes, feature-rich is considered a negative attribute. The terms feature creep, software bloat, and featuritis refer to software that is overly feature-rich.[12] This type of excessive inclusion of features is in some cases a result of design by committee.[13]
To counteract the tendency of software developers to add additional, unnecessary features, the Unix philosophy was developed in the 1970s by Bell Labs employees working on the Unix operating system such as Ken Thompson and Dennis Ritchie. The philosophy can be summarized as: software programs should generally only complete one primary task and that "small is beautiful".[14][15]

An undocumented feature is an unintended or undocumented hardware operation, for example an undocumented instruction, or software feature found in computer hardware and software that is considered beneficial or useful. Sometimes the documentation is omitted through oversight, but undocumented features are sometimes not intended for use by end users, but left available for use by the vendor for software support and development. Also, some unintended operation of hardware or software that ends up being of utility to users is simply a bug, flaw or quirk. Since the suppliers of the software usually consider the software documentation to constitute a contract for the behavior of the software, undocumented features are generally left unsupported and may be removed or changed at will and without notice to the users. Undocumented or unsupported features are sometimes also called "not manufacturer supported" (NOMAS), a term coined by PPC Journal in the early 1980s. Some user-reported defects are viewed by software developers as working as expected, leading to the catchphrase "it's not a bug, it's a feature" (INABIAF) and its variations.
Night Shift is a built in software feature of iOS and macOS. It was introduced in 2016–2017 into iOS in iOS 9.3 and into macOS in macOS Sierra 10.12.4. The feature changes the color temperature of the display towards the warmer part of the color spectrum that reduces some of the blue light from the screen. Apple claims that the feature may help users have a better night's sleep by filtering blue wavelengths from the display, which suppress melatonin biosynthesis. The feature is similar to the functionality f.lux provides.
In software, a spell checker (or spelling checker or spell check) is a software feature that checks for misspellings in a text. Spell-checking features are often embedded in software or services, such as a word processor, email client, electronic dictionary, or search engine.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
