Currently if I want to know what a part is that is referenced in the "Uses" or "Where Used" tab I have to right click and preview the file or go up to the search and find that file and see the preview either in the "preview" or "history" tab. But if this turns out not to be the part I was interested I have to go back to the previous file and look though the "where used" or "Uses" for the next file. A simple thumbnail that shows the part would save alot of time.
