What's new since 1.3.1
• Domain lookup: hover a domain for WHOIS and DNS records
• Keyboard shortcut lookup (Alt+Shift+L) — select an IP/domain or point at it, no hovering needed; hover and shortcut now have separate on/off switches
• Card display time setting (never / 3–60 seconds)
• "Look up this site" button in the toolbar popup (sent only when pressed), with CNAME / IP / name servers
• Reverse DNS (PTR) section with forward check on IP cards
• Copy buttons (whitespace removed), info cards inside small iframes, "too many lookups" notice
• Interface languages: English, 繁體中文, 简体中文, 日本語 — switchable in settings
• Version info and version history in settings
