Before revision:  The apps include demonstrations of molecular visualization at atomistic and coarse-grained levels  , coarse-grained modeling of molecular physics, on-the-fly calculation of experimental observables and comparison to actual data, and simulated chemical reactivity.
After revision:  The apps include demonstrations of molecular visualization at atomistic and coarse-grained levels in interactive immersive 3D , coarse-grained modeling of molecular physics, on-the-fly calculation of experimental observables and comparison to actual data, and simulated chemical reactivity.
