Change the default behavior of thumbnails, especially for families. For the thumbnail, it would be great to turn off the reference planes and reference lines, hide dimensions, and turn on Preview Visibility. That way a maximized version of the family is saved instead of a blurry green crosshair that is useless. It is time-consuming to manually go into each family, turn these items off, turn on Preview Visibility, and save the file just to get a clean thumbnail for users to see. It would be great if the thumbnail could be clearer too.
