“~ 7 ~ Windows needs a universal “Paste Plain Text” or “Paste and Match Style” clipboard option”
This option already exists, in Office at least. See the tag with (Ctrl) underneath what you paste, that has options to paste just the text, merge formatting or match the destination formatting. Those same options are also on the context menu under Paste Options.
Some of these points I agree with but others just show that you really haven’t looked for yourself and as a result think Windows should be Microsoft MacOS 10.
