nwg-launchers is C++ rewrite of sgtk-menu, an application launcher
primarily developed for Sway but also works on other window managers.

Features:
- GNOME-like application grid, with search box and favourites
- Horizontal or vertical button bar, out of a template file
- GTK menu out of commands found in $PATH or newline-separated input
