When I install a desktop in Debian 13, I usually use the KDE Plasma GUI. It's quite close to a Windows interface (to avoid users getting lost), it's quite pretty, and quite customizable.
Sometimes, some applications installed on a Linux system can only be launched from the command line, which isn't always practical for everyday use. We'll see how to enable launching via the KDE Plasma application launcher.
First, open the application launcher and right-click on an application. Then choose " edit an application... "

In our example, we will add an application to launch Firefox in "Safe Mode". Click on " New Item " in the top left corner of the window, and give it a name, for example, " Firefox Safemode ".
In the right part of the window, the settings are as follows:
- Name: Name of the application displayed in the launcher
- Description: Small text that will be placed in parentheses after the application name
- Comment: Content of the tooltip that will be displayed when the cursor remains on the line concerned for a few seconds
- Environment Variables: Variables set when the application is launched
- Program: Name or path of the program to run
- Command line arguments: Arguments passed to the program at runtime
You can also specify the icon that will be displayed next to the name by clicking the square to the right of the fields.
So our example would look like this:

You can then choose which application group the icon will be in, or create a new one. Then click " Save " in the top left corner of the window
By searching the menu, we find our newly added application.
