That is where you can perform maintenance tasks, such as restarting or stopping Classic, rebuilding the Classic desktop, or starting Classic with extensions off.

During this time, the lower layers of the operating system the Mach kernel and the BSD layers on top of it  were re-packaged and released under the Apple Public Source License.
They became known as Darwin. The Darwin kernel provides a stable and flexible operating system, which takes advantage of the contributions of programmers and independent open-source projects outside Apple; however, it sees little use outside the Macintosh community [ citation needed ].
During this period, the Java programming language had increased in popularity, and an effort was started to improve Mac Java support. Aqua was a substantial departure from the Mac OS 9 interface, which had evolved with little change from that of the original Macintosh operating system: it incorporated full color scalable graphics, anti-aliasing of text and graphics, simulated shading and highlights, transparency and shadows, and animation. A key new feature was the Dock, an application launcher which took advantage of these capabilities.
Despite this, OS X maintained a substantial degree of consistency with the traditional Mac OS interface and Apple's own Apple Human Interface Guidelines , with its pull-down menu at the top of the screen, familiar keyboard shortcuts, and support for a single-button mouse.
The development of Aqua was delayed somewhat by the switch from OpenStep's Display PostScript engine to one developed in-house that was free of any license restrictions, known as Quartz.
