Plugin for Max to kitbash like in Modo?

PolyHertz

In Modo there is a menu in the Layout tab that shows preview thumbnails of different meshs you've saved out which can be drag-dropped right into the scene or onto a surface.

Is there any script/plugin for max that lets you preview and drag/drop meshes like that?

If you turn on "Save Viewport Thumbnails" in the preferences. You can use an image viewer app (like XNview) to browse the thumbnails, and drag and drop into the viewport.
