Readdle has released an update to PDF Expert, its iPad app for viewing, annotating and editing PDF files adding full text search across the app’s entire PDF library and several other enhancements. With PDF Expert 3.2 the built-in Document Search feature now goes beyond just the file name allowing a full search of text-based PDFs to make locating documents faster and easier. Users can also now sort files based on name and date by using options found when scrolling past the top of a document list. Additional features include a new eraser tool for handwritten annotations, support of the tab and arrow keys for filling in PDF forms when using external Bluetooth keyboards and improvements to handwriting and wrist protection. The latest update also implements the iOS Data Protection API automatically encrypting all documents in PDF Expert on password-protected iOS devices. PDF Expert 3.2 is available from the App Store for $10.
