Google plans to debut a new user interface (UI) for Chrome’s built-in PDF viewer in November’s Chrome 87.
Details are skimpy, even though the PDF changes were first noticed in March. Most importantly, when a PDF document is opened in Chrome, a toolbar will now appear. When Chrome 85 – the version released in late August – was told to display the toolbar (via a selection in the chrome://flags page), only a place holding message shows (“New PDF Viewer toolbar will appear here.”)
Google asserted that the new PDF viewer would also include a “two-up” view – two pages, shown side by side – the document table of contents and a mode to see added annotations.
