Do you use the Scanner app on your Chromebook? If yes, here is a piece of good news for you. You will soon be to scan multiple documents into a single PDF using the app.
Google recently added a standalone Scanning app to Chrome OS. A new flag that I spotted today in the Chromium Gerrit talks about an upcoming feature for this app.
Enable multi-page scanning in Scan app: Enables creating a single PDF file from multiple flatbed scans.
I get most of my scanning done using my phone these days. However, I can think of the scanning app as being really useful in some situations, especially for schools and businesses. If you are in such an environment, I am sure this will news will make you happy.
