Acorn 4 brings new non-destructive filters, multiple layer selection, new shape tools such as “Stars, Arrows, and a Bezier anchor,” and a revamped UI with the tools palette in a separate window.

Other improvements include enhancements to speed, a new UI for filters dubbed the ‘Merlin HUD’, and Boolean shape operations, and Curves to “Adjust the tonal response and even the individual color channels to perfect the midtones, shadows, highlights, and contrast.”
