PowerToys version 0.90.0 introduces the Command Palette, or "CmdPal," which enhances app launching and user efficiency. Users can access it by pressing Win+Alt+Space, allowing for quick app launches and mathematical calculations. The update also includes enhancements to the Color Picker, which now features improved visual consistency and theme support, the ability to delete files directly from the Peek feature, and support for variables in template filenames in the New+ module. The update is available for download from the PowerToys GitHub page.
