Not only that - it supports PDFs (I annotate the books and papers in it), SVGs, variable fonts, emojis, even spreadsheets - yup, you can do Excel-like calculations; there are built-in browsers, etc. Besides, you can control music and video playback - useful when watching videos and taking notes, you can extract video transcripts, etc. etc. There even exists (albeit quite primitive) a video editor for Emacs.
