Again, weirdly, not a single word on how Windows 95 copied the title bar design and buttons from NeXTSTEP. See, for instance, here: https://guidebookgallery.org/screenshots/openstep42#full https://guidebookgallery.org/screenshots/openstep42#full The “close window” (“×”) button is identical, and Windows 95 re-purposed NeXTSTEP’s “minimize” button into a “maximize” button. But you can still see why NeXTSTEP’s “minimize” button looks that way; it resembles a NeXTSTEP application icon, seen at the bottom on the above screenshot. Windows 95 did not, sadly, copy the very useful behavior of the “close window” button in NeXTSTEP: It changed shape if the contents of a window was not saved, as seen here: https://guidebookgallery.org/screenshots/openstep42#texteditor https://guidebookgallery.org/screenshots/openstep42#textedit...
