TabGroup Master v1.0.0

First stable release of TabGroup Master 🚀

Turn Chrome's flat tab-group strip into a full-screen, nested workspace — fully local, no account, no tracking.

🔥 Highlights

• 🗂️ Nested folder workspace with drag & drop
• 🪟 Free Mode — groups open in their own window, nothing touches your bookmarks bar
• 💤 Frozen tabs — reopen 100-tab groups with almost no RAM
• ⬇️ One-click import of your saved/closed Chrome groups (native host or pure-JS, no install)
• 🧹 Cleanup tools (find unnamed, merge duplicates) with Undo
• 🔎 Accent-aware search across titles and tab URLs
• 🛟 Triple backup: off-profile file + cloud sync + JSON export

🔒 Security & reliability in this build

• All user text HTML-escaped; only http(s)/ftp/mailto links are clickable (blocks javascript: injection)
• Large backups chunked under Chrome's 1 MB limit so restore never silently fails
• Single-Undo bulk delete, deduped render listeners
