"Delete" button missing from Shared PDFs

I use shared PDFs extensively for proofing documents with my team.  As the manager/organize of all these PDFs (upwards of 250 a month), I've gotten very used to how it works.

With the recent update, the "Delete" button was removed from the side panel when a Shared PDF is open.  I'm not sure why it was necessary to remove this button.

Now, it seems the "Delete" button now can only be found when I go back to the "Shared by me" tab and select the document - instead of directly within the document. This creates an very unnecessary two-step to accomplish the simple task of deleting a document. There was already a delete confirmation pop-up to avoid accidentally deleting a PDF.

Please put that button back in the overview tab of Shared PDFs.
