Hello -- I am running a new installation of Composer 2019 and have two questions.  1) I noticed that my Camera Views don't show the diagonal gray appearance in the view thumbnails pane as they used to in 2017. Is this a bug, or a setting that I have to change?  2) I'm working with models created by an outside vendor. Is there any easy way to purge unneeded metadata from the hundreds of parts in this assembly, other than clicking on "properties" for each part and deleting the unwanted metadata?  Appreciate any tips or suggestions.  Thanks!
