What is plugin-plasma-toolbar?

This plugin adds a small toolbar widget for KDE Plasma desktops that shows the status and network speed of Qv2ray, which is a tool used to route internet traffic through proxy servers. If you use Qv2ray on a Linux system running the KDE Plasma desktop environment, this little widget sits in your panel and gives you a live view of what is happening with your connection at a glance. The widget is built with QML, a language commonly used for designing user interface elements in KDE and other Qt-based applications. Installing it involves running a few standard commands that compile and place the plugin into the right system folder so your desktop panel can recognize and display it. Once installed, it acts as a bridge between the main Qv2ray application and your desktop's taskbar. This tool is specifically for people who already use Qv2ray on a Linux desktop running KDE Plasma. For example, if you rely on a proxy connection to access a work network or browse privately, you might want to confirm the connection is active without opening the full Qv2ray window. This widget gives you that information directly on your screen, similar to how a Wi-Fi indicator shows your signal strength. The README is very short and does not go into detail about exactly which data points the widget shows, such as specific upload and download speeds or connection status icons. It simply states that the plugin displays information on the KDE Plasma panel. The project is a small, focused utility licensed under the GPLv3 open-source license.
