  • Add commands, buttons, menus, and other UI elements to the IDE

  • Add tool windows for new functionality

  • Extend IntelliSense for a given language, or provide IntelliSense for new programming languages

  • Use light bulbs to provide hints and suggestions that help developers write better code

  • Enable support for a new language
