Users have told us that context switching between Markdown mode and preview mode slows them down. We want to minimize the friction between you and sharing your research with the world, so Markdown-dependent editing had to go. With arbitrary reordering, cut+paste, and undo history for everything (even panel grids!), making reports should feel much more natural now. Furthermore, WYSIWYG makes it easier for us to add new advanced features in the future, like video embeds, commenting on specific text selections, and real-time collaboration.
