KDE is a popular Desktop Environment for UNIX-Based Operating Systems, ranging from Linux to various flavors of BSD. Originally created by Matthias Ettrich in 1996, the KDE project was founded upon the premise that it should be a "complete graphical environment," implying the creation of a fully featured and richly tooled Desktop Environment which KDE has become in the modern era.

Features

KDE Plasma alone merely provides a Desktop Environment - this is no understatement of its base suite, which includes fully featured Settings application, Dolphin, a robust file manager, Discover, an application store for Flatpak, and a few other base tools. However, the KDE Project itself offers a multitude of software - according to their website, they have successfully created "over 200 applications" for the modern desktop. Some of their most important projects have made a significant impact on the Linux universe:

• Krita - a fully-featured suite for artistry such as painting and even animation. Often compared to CLIP STUDIO, Procreate, and others.
• Kdenlive - a movie editor for film-making, with a few transitions and effects. While it has been criticized for being either lackluster, difficult to use, and failing to work with some GPUs, it is still an effective option for many beginners [CITATION NEEDED]. Kdenlive, as a sample, was used explicitly used to create this video to demonstrate some of its basic capabilities.
• Ark - a file compression and decompression tool that supports a wide range of formats commonly used throughout the internet. Despite the lack of RAR support, Ark is just as versatile and arguably even competes against applications like WinRar.
• Kate - a text editor that not only supports syntax highlighting - a must for quick edits to source code - but has a plethora of features that make it a suitable choice for lightweight programming.
• Filelight - a very useful tool for assessing how much storage on your machine is in use or free, which does not only scale to your installation disk but also to external media as well.

Edit Mode

"Add Widgets..." bar on KDE Plasma

Part of KDE's robust configuration is its capability to enter "edit mode" - essentially, from edit mode, you have full access to the layout of your system's panels and widgets. Within this menu, there are several elements:

• Widgets - in and of themselves, widgets can do two possible things in the layout of your desktop;
  • They can be added, often seamlessly, into one of your panels for easy management;
  • They can be added directly onto your desktop - that is, the empty space you have without any windows open.
    • Note that this does imply, for laptops, a small yet somewhat noticeable drop in battery life. If you want your laptop to last, make sure you minimize your plugins.
• Get New Widgets... - Here, you can find some often useful widgets made by the community. Be sure to check for quality - sometimes, widgets can be very buggy.
• Add Panel... - These are the bars of which that house widgets or trays, pictured below. Depending on your composition of spacers and widgets in between, panels can serve multiple purposes beyond just an Application Launcher like on Windows.
• Configure Desktop and Wallpaper... - A simple user interface to change your wallpaper and adjust its appearance.
  • These can be modified by plugins.
  • NOTE: This was written before the KDE 6.1 update. There are not many major functional differences, most are visual.

Desktop Effects

Desktop effects allow for additional responsiveness and appearance tweaks for the KDE desktop. After the Plasma 5 update, many widgets and other features were soon deprecated or removed altogether, yet there is still a sizable enough amount of extra effects to use.

• Accessibility - Helps the visually impaired or other people that may struggle to use a desktop without additional aid.
• Appearance - Different tweaks, animations, and additional features that can be added or removed to allow for the adjustment of the KDE desktop's visual elements.
  • EX: Wobbly Windows allows for your windows to have additional elasticity when dragged and interacted with..
• Focus - Determines the behavior of stacked windows and popups.
• Peek at Desktop Animation - Animation played when using Peek at Desktop.
• Tools - Used primarily for debugging with the base tools.
• Virtual Desktop Switching Animation - Seen when changing virtual desktops.
• Window Management/Open and Close Animations - Determines the visual behavior of open windows, as well as determining the behavior of them when interacted with.

There are also extra effects that can be obtained either through the package manager or through Get new effects... on KDE. For example, kwin-effect-rounded-corners-git on the Arch User Repository allows for corner rounding on KDE for both X11 and Wayland on active and/or inactive windows.
