Rusty Tab Manager

A Chrome extension that keeps your tabs organised automatically.

Features

• Auto-grouping — tabs are grouped by second-level domain as soon as they open. All *.google.com tabs go into a google group, all *.github.com tabs into a github group, and so on.
• Custom rules — define your own grouping rules via the popup UI. Map multiple domains to a single named group (e.g. group google.com, youtube.com, and gmail.com under "Google"). Rules are synced across devices via Chrome storage.
• Auto-collapse — switching to a tab collapses all other groups, so only the active group is expanded at any time.
• Sorted groups — tab groups are kept in alphabetical order at all times.
• Keyboard shortcut — Cmd+Shift+0 (Mac) / Ctrl+Shift+0 (Windows/Linux) expands all groups at once.
