Changes Log

World Map Zooming & Panning

• Zoom Functionality: Implemented map zooming with support for magnification levels.
• Vertical Panning: Added latitude offset tracking to allow vertical scrolling when zoomed in.
• Controls Update:
  • Dedicated WASD keys for map movement (Up, Down, Left, Right).
  • Added Q and E (plus + and -) for zooming out and in.
  • Disabled mouse scroll wheel for zooming/panning per user preference.
• Global Keys: Removed q as a global quit shortcut to avoid conflict with the new zoom-out key. Users should now use Ctrl-C to exit.

Rendering Improvements

• Pole Crossing Fix: Refactored line drawing logic to correctly handle segments crossing the North and South poles, preventing "stretched" horizontal line artifacts.
• IDL Seamless Wrapping: Improved International Date Line (IDL) wrapping logic for both lines and text, ensuring smooth transitions when panning or zooming.
• Higher Resolution: Increased the step resolution for the day-night terminator and visibility circle calculations by 5x for smoother rendering at high zoom.
• Multi-Offset Rendering: Implemented a draw_text helper to render satellite labels and symbols at multiple 180-degree offsets to handle map wrapping perfectly.

Satellite Groups & Timeline Enhancements

• Timeline Controls: Added Left and Right arrow keys for precise time adjustment.
• Group Search: Added a new search feature to the Satellite Groups widget:
  • Press / to enter search mode and filter groups by name.
  • Title bar displays the current search query.
• Group Navigation: Added Up and Down arrow keys for navigating the list.
• Group Selection: Added Spacebar as a keyboard shortcut to toggle selection of the highlighted group.

Documentation & Localization

• Updated docs/keymap.md with the new keyboard and mouse interaction model.
• Updated locales/en.yml with new translations for search and zoom features.
• Updated the in-app Keymap popup (?) to reflect all control changes across all widgets.

Technical Fixes

• Dependency Compatibility: Downgraded the fixed crate to v1.28.0 to ensure compatibility with Rust 1.90.0.
• Stable Rust Support: Replaced the unstable Duration::from_mins with a stable alternative.
• Type & Lifetime Safety: Resolved various compilation errors related to type mismatches and borrow checker constraints in the new widget logic.
