Use VCL Styles at Design Time!

VCL Styles now provides design-time support: Prototype stylish UIs even faster by seeing immediately at design-time how your styled forms and controls will look when running. Viewing at design time how styles will impact the UI at runtime improves the design and testing process for modern UIs. Creating better UIs faster is especially useful when working with per-control styles.
