1. Removed animations and transitions
   All CSS transitions and animations have been removed from styles.css for faster UI performance.
2. Added icon references to manifest
   Updated manifest.json to include icon declarations. You'll need to create these icon files:

icon-16.png (16x16 pixels)
icon-48.png (48x48 pixels)
icon-128.png (128x128 pixels)

1. Removed stats tab completely

Removed from navigation in popup.html
Removed all stats-related code from popup.js

1. Enhanced History and Analytics UI

History tab: Added icons, improved spacing, better visual hierarchy with cards, enhanced rename/download buttons
Analytics tab: Added summary section, improved chart containers with icons, better insight cards with bullet points

The extension is now optimized for speed with a cleaner, more focused interface. The visual improvements include better spacing, shadows, icons, and a more modern card-based layout for both History and Analytics views.
