Shapes with live settings, shape editing, knife and hole tools, drawing shapes onto other objects, combining objects (add / subtract / overlap), copies, thickness, painting with stickers and layers, a Layout tab, a Print tab with checks, packed .fry files with autosave, export to GLB, glTF, FBX, OBJ, 3MF, STL and PLY, folders in Layers, its own crash screen, and a website for GitHub Pages in docs/.
