github jmoenig/Snap 4.0.10

Named "Walldorf" to honor SAP's sponsorship Snap’s first update in 2017 concludes a series of improvements and enhancements to the user interface. While previous releases in 2016 focused on data and its visualization (tables, linked lists and first-class sprites) v4.0.10 revisits how you work with blocks, adding such long sought-after features as UNDO/REDO, auto-wrapping (inside-out nesting of control structures), entering formulas using the keyboard, refactoring variables (renaming all accessors in scope), browsing and previewing libraries, supporting hierarchical drop-down menus for input slots and extending the typography for block labels. In addition, this release also improves the UI for working with resources (pictures, SVGs, sounds) and projects.
