[latitude*1e7, longitude*1e7]
- Minute-based color segmentation (10-color palette)
- Start marker (green 🚀) and end marker (red 🏁)
- Sampled intermediate points
- Auto-zoom to route bounds
- Hover Tooltips: Show time, lat/lng on mouseover (no clicking required)
CPU Usage Tab
- All Apps Displayed: Shows complete CPU usage for every app (no 50-app limit)
- Sortable Table: Click column headers to sort by usage, user, kernel, or app name
- Detailed Breakdown: User % and Kernel % for each application
- Summary Statistics: Total CPU usage across all processes
Memory Tab
- Comprehensive Memory Analysis: Full MEMINFO parsing for all apps

- Sortable: Order by any memory metric
TOP Output Tab (NEW)
- System Overview:
- Thread statistics (total, running, sleeping, stopped, zombie)
- Memory usage (total, used, free, buffers)
- Swap information
- CPU breakdown (user, nice, sys, idle, iow, irq, sirq, host)
- Process Table: Complete process listing with sortable columns
- PID, TID, User, Priority, Nice
- CPU percentage, State

- PCY, Command, Name
Display Tab (NEW)
- SurfaceFlinger Visualization: Visual representation of Android display layers
- Display List: Shows all displays with resolution and layer count
- Interactive Layer Canvas:
- Visual representation of all layers with z-order
- Each layer shown with unique color
- Scaled to fit canvas while maintaining aspect ratio
- Layer Controls:
- Checkbox for each layer to show/hide
- Click to toggle individual layers on/off
- See layer stacking in real-time
- Layer Details:
