Word, Excel and PowerPoint, rebuilt for free

Microsoft Word, Excel, PowerPoint and even AutoCAD, rebuilt for free: WordCraft, GridCraft, DeckCraft and CADCraft from the ArtCraft team, open source under MIT or Apache-2.0. They open .docx, .xlsx and .pptx files and run on Mac, Windows, Linux and in the browser. SoundCraft (Pro Tools) is on the way. Free on GitHub (storytold). Still early, so don't cancel Office just yet. Which app should they rebuild next?
