  🎯Why Change Subject Lines in Gmail?
  The subject line is the first thing you see. Whether you're managing a busy inbox, replying/forwarding emails, or just want clearer previews — changing the subjects helps you make them more descriptive, stay organized, and work faster.
  
  What You Can Do
  Everything happens right inside your Gmail interface:
  ✅ Edit subject from the email list view — click, type, and save.
  ✅ Edit subject from the email detail view — same experience.
  ✅ Smart reply/forward reminder — a gentle reminder appears when you're using the original subject, with one-click switch.
  ✅ No data loss — your custom subjects stay even after browser restart.
  ✅ Works entirely in the browser — no server-side email modification.
  
  Perfect For
  🏆 Busy Professionals – Keep your inbox clean and organized with subject lines that actually make sense.
  🏆 Sales & Support Teams – Forward emails with clean, relevant subjects without altering original threads.
  🏆 Project Managers – Rename email threads to match project names or task names.
  🏆 Anyone Who Organizes Emails – Keep your inbox clean and meaningful with custom subject lines.
  
  How to Use This Extension
  1. Open Gmail in your browser.
  2. Open an email or choose one from your inbox list.
  3. Click the Edit subject button in the toolbar.
  4. Enter your custom subject in the popup window and click Save.
  5. Reply and forward normally — if the email has a custom subject, you'll see a gentle reminder showing you how to switch to it.
  
  Why Use This Extension?
  Unlike other extensions that require high-level permissions to recreate emails, we take a completely different approach:
  ☑️ No server-side email modification – We never modify your original email data.
  ☑️ No high-level permissions – Works entirely in the browser interface with minimal access.
  ☑️ Easy to revert – Subjects return to original if you disable or remove the extension.
  ☑️ Transparent by design – What you see is what changes; nothing is altered on the server.
  
  🔒 Privacy & Security
  We only store your email address, email IDs, and subjects to sync custom subjects.
  The data is encrypted and stored securely on our servers.
  No email content is ever read, stored, or transmitted.
  We do not track your email activity or sell any data.

  2. This is a visual enhancement tool. It only changes how subject lines appear in your Gmail interface — the actual email data on Gmail's servers remains unchanged. Searching by the custom subjects or viewing emails in other clients will still show the original.
