#
# Install GUI modifications for NFL (No Foreign Land) Tracking
#
# This script:
# 1. Copies PageSettingsNflTracking.qml to the GUI directory
# 2. Patches PageSettingsGps.qml to add NFL Tracking (inserts between Format and Speed Unit)
# 3. Restarts the GUI
#
# Note: These changes will be lost on firmware update. Run again after updating.
#
# Usage:
#   ./install_gui.sh          # Install GUI modifications
#   ./install_gui.sh --remove # Remove GUI modifications and restore originals
#
