Copy Assets/Editor and Assets/Editor Default Resources folders into your project and the built-in Mesh Inspector will be overridden with the updated one. Should work with Editor versions 2019.3 and up.
The top part of the Inspector was updated to display information about mesh data format, memory usage, submeshes etc.
Middle Mouse Button (Scroll Wheel) click and hold - Pan

Left Mouse Button - Rotate
Right Mouse Button - Rotate Directional lights
F - Focus object (resets pan and zoom, but not rotation)
The Mesh Preview window allows meshes to be viewed in one of the following ways:
A simple shaded preview of the Mesh.
When the mesh has multiple sub-meshes, they are tinted with unique colors. The colors are listed in the top inspector part for each submesh:
Previews a Mesh with a checkerboard texture applied. You can use the slider next to UVChannel dropdown to adjust the tiling of the texture.
Previews unwrapped UVs. Any UV Channel can be previewed, if available. The view can be zoomed and panned, and initially shows 0..1 UV range.
Previews Vertex Colors of a Mesh.
Preview Mesh Normals. We've opted to not displays normals as tiny vectors poking out of vertices, since it feels like without full-on navigation inside the preview window, they would just be a mess for non-trivial meshes.
Preview Mesh Tangents. We've opted to not displays tangents as tiny vectors poking out of vertices, since it feels like without full-on navigation inside the preview window, they would just be a mess for non-trivial meshes.
Preview Mesh Blendshapes. An additional drop down is displayed when this option is selected where you can choose which blendshape to display.
