✨ New Features

• Increased URL Length Limit - URL character limit increased from 256 to 2048 characters to support long URLs such as signed cloud storage URLs or URLs with extensive query parameters

🎨 UI Improvements

• Added help text below the Image URL field showing the 2048 character limit

• Added GitHub repository link in the web interface footer

Full Changelog: v0.1.1...v0.2.0

v0.1.1

What's Changed

🐛 Bug Fixes

• Fixed: WiFi credentials wiped when saving Display settings - Clicking "Save" or "Apply" on the Display tab no longer overwrites your WiFi credentials. Previously, this bug caused the device to lose WiFi configuration and fall back to AP mode on the next boot.

📝 Documentation

• Added "Refresh Interval Priority" section to README explaining how schedule intervals take precedence over the default interval
• Clarified that saving Display tab settings does NOT affect schedule configuration

🎨 UI Improvements

• Added helper text to the Display tab's Refresh Interval field explaining it's used as a fallback when no schedule is active
