Microsoft can't do this with Windows 95, though they were able to get WinNT to do it poorly. System 7.5 added more features. And an OS-wide 3D format that allowed cutting and pasting between apps, improved networking, and drag and drop editing. Folder and desktop views are now controlled from the finder menus rather than a separate control panel. Everything's 3D. Simultaneous copying, deleting, and reorganizing is possible with the multithreaded finder.
Contextual menus add more flexibility.
Pop up drawers and collapse buttons give you new ways to minimize a window. Organize your desktop by list views. And so on. Allegro, due soon, is even faster, consolidates the Internet controls, and adds a much improved search technology that can search your computer or the net. Again, refining what works.
