wtf is tab-ban-board?

Tab-Ban Board is a Chrome extension that replaces your new tab page with a Kanban style board of all your currently open tabs, arranged into columns by root domain. All your GitHub tabs land in one column, all your Google tabs in another, and your local development servers get their own column too. It is described as a Kanban remix of an earlier extension called Tab Out, rebuilt with a shadcn UI based interface. Columns are arranged with any existing Chrome tab groups shown first, keeping their original name and color, followed by columns grouped by domain sorted by how many tabs are open, and finally a single Other column that collects every domain with just one lone tab so the board does not sprawl. Sites hosted on shared platforms are handled so that, for example, two different people's github.io pages get separate columns rather than being merged together, and localhost tabs get their own column with port numbers shown so you can tell different local dev servers apart. You can click any card to jump straight to that tab, close a single tab or an entire column of tabs in one click, and duplicate tabs collapse into a single card with a count badge and a cleanup option. The board updates live as tabs open, close, and navigate, and it supports both light and dark mode based on your system setting. According to the README, everything runs locally at runtime, favicons come from Chrome's own cache, fonts are bundled into the extension, and no data leaves your machine or is sent to any external server. The extension is built with Chrome's Manifest V3, React, shadcn UI components, and Tailwind CSS, and the already built extension files are committed to the repository, so installing it just means loading the extension folder as an unpacked extension in Chrome, no build step required. It is released under the MIT license as a derivative of the original Tab Out project.
