New for this version 1.4.3727.0 is:
Now you can convert your pictures to PDF files with selectable text, in addition to Word and PowerPoint files, and save them to OneDrive.
I gave this new feature a quick whirl:
An intro splash screen shows the main new feature; 'scanning' a page from an old manual as a test....
Setting up the save to OneDrive and in the formats I want...; (right) the processing and upload in progress.... For my page, it took about ten seconds.
Opening the PDF file in OneDrive, it still looks like a photo, BUT the text is now fully searchable - and, on the right platform, selectable and copy-able too.
Very cool. You can download Office Lens in the Store here, for free.
