Today in iLounge Deals, we’re offering MarginNote Pro for Mac for only $24.99 — that’s 50% off the regular price. This tool will help you learn something new every day and commit that knowledge to memory, with powerful reading features for students, teachers, researchers, lawyers, or even the naturally curious. You can quickly organize, study, and manage large volumes of PDF and EPUB files, while also taking notes right in the margins, creating mind maps, reviewing flashcards, and more, all in one place. Notes can include voice clips, handwriting, pictures, hashtags, and even web content, and you can search through your hashtags across your complete notes, or within a specific book, and export everything to other tools like Anki, iThoughts, MindManager, OmniOutliner, and Evernote, and keep everything in sync using Dropbox, Evernote, or iCloud.
