Option to define some object types as "second-class" when they don't need a dedicated page

Hi, the first thing I mean is I'd like to have is an option to filter out some objects from the graphs.

An example: when I create a book object I will link it to its author, its field of science, its publisher.

But besides that I'll also set an image of the cover, a weblink to its wikipedia page, a weblink to its amazon page, a weblink to a review of this book, a weblink to a youtube presentation of the book, a pdf with the content of this book.

I'll need the graph to show the first links (author, FoS, publisher) but images, weblinks and associated files just clutter the graph without giving added value (most often their name is the same as the book itself which makes things difficult to sort out)

Moreover, when a property accepts multi-select, the values may be listed on the same "branch" of the graph.

Linked to this request, I think this option could also be used to declutter navigation. Most often (at least for me), images, weblinks and associated files don't require additional notes, since they are themselves "notes" for the main book object. So instead of opening a seperate page for them I would find much more convenient to have the following default behaviors when clicked:

• image -> display full size image
• weblink -> open link
• pdf -> open pdf
