v2.0 release.

• New overlay UI. Opens next to the page instead of in a separate popup.
• Marketplace listing prices show in the WHOIS panel when a domain is parked for sale.
• Quick search bar in the popup checks multiple TLDs at once.
• Caching rewritten so repeat lookups are faster.
• More TLDs supported through the updated RDAP routing.
• On chrome://, the Web Store, and error pages, a compact fallback popup runs the WHOIS check directly.

New Features:
Affixes: Search for domain name variants using prefixes and suffixes. Enable the toggle in the search bar or directly from a WHOIS result to instantly explore available alternatives built around your keyword. Read
Improvements:
Background Links: All external links (visit domain, marketplaces) now open in a background tab — the popup stays open so you can keep researching.
