## Description

Take control of your browsing flow with Zen History & Analytics, a local-first sidebar built for focus and productivity.

Core Features:• 7-Day Activity Heatmap: Visually scan your browsing frequency. Click any day to instantly filter your history.• Smart Tagging & Search: Assign custom hashtags (#work, #learning, #wasted) to domains. Search by tag to instantly filter out the noise.• Proactive Domain Blocker: Stop autopilot browsing. Blocked domains redirect to a calm interstitial page, requiring a conscious click to proceed.• Ambient Reflection: View a productivity score based on your tagged habits, and see estimated RAM usage across your open tabs.• Tab Purging: Instantly close all background tabs to reclaim system memory with a single click.
Privacy First:Zen does not sync, phone home, or track you. All history queries, tags, and blocklists are stored strictly in your browser's local storage.
