 ## Immediate Priorities
 
-### More Accurate Integration Methods
-**Current:** RK4 (Runge-Kutta 4th order) integration
-**Proposed:** Newton-Raphson propagation for higher precision
-
-**Benefits:**
-- Improved accuracy for long-term orbit predictions
-- Better handling of near-parabolic trajectories
-- Reduced numerical drift in N-body systems
-
-**Implementation Considerations:**
-- May require adaptive timestep sizing
-- More complex than RK4
-- Trade-off between accuracy and performance
-
-### Reference Frame Switching
-**Current:** Fixed global/local coordinate frames per body type
-**Proposed:** Dynamic reference frame selection based on orbital regime
-
-**Use Cases:**
-- Spacecraft transitioning between planetary SOIs
-- Interplanetary trajectories needing optimal precision
-- Multi-body perturbation modeling
-
-**Benefits:**
-- Optimal numerical precision for all orbit types
-- Automatic frame selection based on physics state
-- Better simulation stability during SOI transitions
