Vivaldi Tab Switcher for Niri (via CDP + fuzzel)

A bash script that lets you search and switch between Vivaldi browser tabs using fuzzel as a dmenu-style picker, powered by Chrome DevTools Protocol (CDP). Designed for the Niri Wayland compositor.

What It Does

1. Queries Vivaldi's remote debugging endpoint for all open tabs.
2. Presents tab titles in a fuzzel popup so you can fuzzy-search.
3. Activates the selected tab via CDP.
4. Focuses the correct Vivaldi window using niri msg.

Prerequisites

Dependency	Purpose
Vivaldi	Browser with CDP remote debugging enabled
curl	HTTP requests to the CDP endpoint
jq	JSON parsing
fuzzel	Wayland-native dmenu alternative
niri	Wayland compositor (scroll tiling)
