This is a single-file Python application that provides a menu-driven interface (via dmenu, rofi, wofi, bemenu, etc.) for managing NetworkManager connections on Linux. It allows users to connect to WiFi, VPN, Wireguard, GSM, Bluetooth, Ethernet, and VLANs; enable/disable networking, WiFi, WWAN, and Bluetooth; delete connections; rescan WiFi; show WiFi passwords; and launch the connection editor. The script uses PyGObject to interact with NetworkManager over D-Bus, with asynchronous callbacks and a GLib main loop. Configuration is stored in an INI file, and the script supports multiple launchers with per-launcher flags for passphrase entry and highlighting. The code is well-structured, with clear separation of concerns (action creation, menu display, async callbacks), and includes workarounds for older library versions. It is a mature, actively maintained tool with a Nix flake for development and a GitHub release workflow.
