There are some tools which are now missing. But are simple to write
- jwm-xdg-menu - script which reads XDG desktop files and outputs jwm XML config to generate menu (written).
- jwm-xdg-autostart processes XDG-style .config/autostart directory and runs every desktop file it found there.
- wifi-applet - tray applet to control wpa_supplicant with better interface than wpa_gui
