dbus_hooks

dbus_hooks is forked from an upstream crate called ksni and modified to fit Thunderbird's needs. You can find the

A Rust implementation of the KDE/freedesktop StatusNotifierItem specification.

This crate is used in the Linux system tray icon.

    // We can modify the tray

Will create a system tray like this:
