Koi is a program designed to provide the KDE Plasma Desktop functionality to automatically switch between light and dark themes. Koi is under semi-active development, and while it is stable enough to use daily, expect bugs. Koi is designed to be used with Plasma, and while some features may function under different desktop environments, they are unlikely to work and untested.
Koi was written as a project to practice QT by a novice programmer, expect code to be written sloppily.
Koi is designed to be very simple to use. After the initial run of Koi, settings for the light and dark presets will be empty, all you need to do is select which themes you would like for Koi to manage and select your desired themes by clicking the Preferences button.
If you would like that Koi switch between your light and dark settings automatically, you can select this option in the main page of the program, and choose between following a user set schedule, or at sunrise and sunset (planned/scheduled feature). To switch between light and dark manually right click the tray icon and select the desired preset, or do so from Koi's main window.
In order to have Koi started at login, you can do so with the KDE Plasma System Settings.
Search for: Autostart

"
Plasma version 6 navigate to System Settings -> System -> Autostart, and select "+ Add...
-> + Add Application

In addition, it is recommended having the option to Start Koi hidden checked, this will prevent Koi from popping up every time you start your operating system.
