About
Now with a built-in Focus Timer to boost productivity during calendar events. 🌟✨ KEY FEATURES ✨🌟 🎨 Google Calendar Color Categorization: Assign categories to Google Calendar's existing color palette, making it easier to remember the purpose of each color. For example, red could represent "Critical," blue "Learning," and green "Finances." 🖌️ Custom Color Groups: Add custom color groups that appear in the color picker on calendar events. Each color in the group can be customized with a unique color and label. ⏱️ Focus Timer: Start a productivity timer directly from any calendar event. Track your focus time, get completion sounds, and build better work habits. 🔍 Eyedropper Tool: Pick any color from the screen to use in your custom palette. 🔄 Reset and Disable Options: Clear all custom colors or disable them to use only categorization with Google's default colors. 🧩 Templates for Easy Setup: Pre-made templates including Time Blocking, Priority, Energy Levels, Schedule Type, Projects, Focus Mode, Mood, and Value. ⚠️🚨 IMPORTANT NOTES 🚨⚠️ 🛠️ Dependency on Google Calendar Layout: This extension relies on Google Calendar's current layout. Changes by Google may temporarily break features. If this happens, reach out via email: [email protected] or visit: https://humanquest.net 💻 Desktop-Only: Chrome extensions don't work on mobile. For mobile, use Google's core colors. 🖌️ Changes Apply to Existing Events Only: New events need to be saved first before colors can be applied. 🙏 Free Extension: This is completely free. Please reach out with issues rather than leaving a negative review. 📋 VERSION UPDATES 📋 🆕 v0.2.4 - Gmail Sidebar Support • Custom colors now appear in Gmail's sidebar calendar — click the Calendar icon in Gmail and your event colors should show up v0.2.3 - Storage & Color Reliability • Fixed custom colors reverting on page refresh — The local storage fallback now correctly reads chunked data, so your colors persist even when sync storage is temporarily unavailable. • Fixed potential infinite loop in storage sync — When Chrome's sync state changes (e.g. signing in/out), the extension no longer risks getting stuck in a recursive loop. • Fixed event viewer dialog coloring — The event detail popup no longer gets incorrectly painted with the event's custom color; only the color dot indicator is updated. v0.2.2 - Storage Health Warnings • Storage Health Warnings - Get notified when storage is running low, blocked, or when using incognito mode. Helpful tooltip explains what's happening and how to fix it. • Focus History now syncs across devices - Your timer sessions are now stored in synced storage, so your focus history follows you across computers.
