LEAD2WWDC: Don’t expect new Macs, iPads, Apple Watch
Apple still has a bunch of new devices up its sleeve for 2018 — not including the new iPhone lineup — but we won’t see any of it at WWDC.

A month or so back I was searching for a PDF app that would use the native Files browser on the iPad, but add features not available in Files app’s built-in PDF viewer. The result of that search was PDF Viewer, an app that is almost impossible to find on Google, but which is simple enough to be perfect for many people.
