All KDE-based distros provide everything you need to work on the system from the kickoff menu.
What is the kickoff ?
Kickoff is the default application launcher and menu system for the KDE Plasma desktop environment. It provides a user-friendly interface for launching applications, accessing system settings, and searching for files and documents. Kickoff is designed to be easy to use and navigate, even for new users.
Other KDE-based distros may use different application launchers, such as KMenu or KRunner. However, Kickoff is the most popular and widely-used launcher for KDE Plasma because it includes a powerful search function that can find files, applications, and settings.
