The continuous advancement of geophysical modeling tools has been pivotal in elucidating the complexities of Earth's lithospheric structures. The latest developments in the software package IGMAS+  have introduced innovative techniques for 3D and 4D gravity and magnetic field modeling, combining interactive user control with cutting-edge optimization algorithms. Among these advancements are the integration of space-warping concepts and the Covariance Matrix Adaptation Evolution Strategy (CMA-ES), which provide enhanced precision in inversion processes while preserving model topology. These methods enable the resolution of previously challenging geological scenarios, such as salt dome geometries and rift basin formations. Case studies illustrate the impact of these developments: the Liguro-Provençal Basin's evolution was revisited using gravity field analysis to assess its rifted nature, while applications in the North German Basin demonstrated the effectiveness of the space-warping technique in refining salt dome structures. These examples highlight the added value of such versatility in addressing regional and global geological challenges through multi-disciplinary modeling approaches. By merging forward modeling and interactive inversion with novel numerical methods, the new version of the software provides a robust tool for geoscientists aiming to integrate diverse datasets into comprehensive models. This work underscores the importance of user-driven innovations in geophysical software, pushing the boundaries of how subsurface structures are explored and understood.
