Get More Productive on your iPad: Notebooks 8.1 adds Split Screen Mode Posted 8/18/2015 at 13:51 UTC in iOS by gnye@amdesign.net | Permalink | Tweet Independent developer Alfons Schmid is pleased to announce Notebooks 8.1 for iPad and iPhone, an upgrade to his productivity application which integrates text processing with task management and document organization. The latest update adds a split screen mode which shows two documents side by side on an iPad - a big advantage when copying from a draft into the final document, previewing a Markdown document while editing its plain text, or taking notes while reading a PDF document.
