 - **Development of a GUI or CLI**: We welcome contributors to build a graphical user interface or an interactive command-line tool similar to *XFOIL*, allowing users to control simulation parameters and view flow visualizations more intuitively.
 - **Improved airfoil support**: Extend the geometry module to handle *arbitrary airfoil geometries*, including NACA or imported `.dat` formats, and automatically generate surface panels with smooth curvature handling.
 - **Fluid–Structure Interaction (FSI)**: We are working on incorporating structural flexibility into the solver for *2-way FSI* simulations with deformable airfoils.
-- *3D extension*: The roadmap includes extending PANKH from 2D unsteady panel methods to full *3D vortex-lattice-based simulations* in the near future.
