v1.2.1

• Updated extension icon: title bar dots now use colored accents (red, blue, teal)
• Added 128px icon size

v1.2.0

• New Timeline View: visualizes tab history as colored vertical lines with column-packed layout
• 8 color presets for track lines to distinguish different tab columns
• "Edges only" toggle: show favicons only at the start/end of each tab's range for a cleaner view
• Improved snapshot deduplication: collapses duplicate tab sets caused by tab reloads or extension restarts
• Smarter column packing: reuses columns when tabs have gaps in their presence, reducing horizontal width
• Fixed change detection in List View (now properly detects tab close events, not just session count changes)

v1.1.0
- Fix: tab close events were missed when the background event page was suspended and restarted. Sessions now store tab IDs and the active session map is
rebuilt from IndexedDB on wake.
- Fix: URL redirects (e.g. x.com → x.com/) no longer create duplicate snapshots. URLs are normalized before comparison.
- New icon: Browser Timeline design matching the monochrome theme.
- Viewer auto-refreshes every 5 seconds with a circular sync timer indicator.
