Compact Windows are a key feature of Big Business and when Auto Zoom functions were added, original-size windows were called Classic. They are now called Compact.
Compact windows are designed to be intuitive and fast and to work well in tight space. If you are working on a single screen, using multiple apps, you will appreciate the size.
Within a window, only preset options appear, the contents never shift, data entry is fast and consistent, and keyboard shortcuts work 100% of the time to speed through.
