fvwm-window-search 2.0.0
A window switcher: search for windows interactively using a patched dmenu utility (comes with the gem). This was originally made for Fvwm, but it's been fully rewritten to work out-of-the-box with any stacking window manager. Requires jansson-devel C library installed. It differs from rofi & co in that it activates (brings up) windows _during_ the search.
