Press F12 or use ☰ → Developer tools to open the full Chromium DevTools — inspector, console, network, sources — docked to the right of the window and resizable. It follows whichever tab is currently active. Close it with the ✕ in its header, or by pressing Esc while it's focused. Like the rest of Vodou, it runs on the off-the-record profile and keeps nothing between sessions.
