SATRIA LAUNCHER v1.5

Version 1.5 (Release Date: February 19, 2026)

✨ Added

• Dashboard Popup: Replaced AssistantPopup when clicking the dock avatar with a bottom sheet design featuring a pill bar. Supports drag gestures (automatically snapping to 45% or near fullscreen) and scrolling.
• 4 Interactive Tool Cards in Dashboard:
  • Weather: Displays weather information via the Open-meteo API (no API key required).
  • Money Exchange: Checks currency exchange rates via the open.er-api.com API.
  • To-Do List: Daily task tracking stored directly in memory (RAM) to keep it incredibly lightweight.
  • Countdown: Day countdown timer featuring a custom, pure React Native calendar date picker.
• Real-Time Preview: Additions or changes to the To-Do List and Countdown now update instantly on the dashboard preview without needing to close and reopen the popup.

🔄 Changed

• Dashboard Header Layout: The avatar is now centered vertically, positioned alongside a digital clock that updates every 10 seconds and the assistant message area.

⚡ Optimized

• RAM Usage (Idle & Active): Removed the refreshApps() call that triggered every time AppState became active (when returning from another app) to prevent unnecessary memory consumption.
• App Icon Rendering: Removed hundreds of Animated.Value nodes in SafeAppIcon (the app grid) and replaced them with standard state-based opacity control.
• TypingIndicator Animation: Consolidated 3 separate dot animations into 1 synchronized component to reduce rendering load.
• FlatList Performance: Reconfigured default render limits to ensure off-screen items are recycled much more aggressively.

🐛 Fixed

• Close Animation Lag: Fixed the 0.5-second freeze when dragging the dashboard down to close by manually tracking the real-time frame position and removing stopAnimation.
• Modal Closing: Removed all animation durations when closing modals or the dashboard so they close instantly without any delay.
• Date Picker Crash: Removed the @react-native-community/datetimepicker external dependency that caused a blank screen when opening the dashboard, replacing it with a custom native React Native calendar component.
• Drag & Double Positioning Bug: Fixed position calculations that previously threw the sheet off-screen, and adjusted the panResponder area so the sheet can still be dragged from the top even when positioned over a ScrollView.

🗑️ Removed

• The automated assistant message feature that operated based on a daily time schedule.
• All logic, state, and UI components related to the red dot notification badge on the avatar and dock.

Feedback and contributions welcome!
