What I'd like seen addressed is the insistence of every app trying it's best to include formatting information, even so far as to include table cells formatting data in the clipboard. I've found copying this format info useful maybe twice(?) in my 50+ year life and otherwise it is a huge PITA. Including having email clients crash or refuse to properly undo weird table formats that unintentionally get pasted over. Instead, I have to paste to an open editor in a terminal window and then do another copy and paste to the destination to most reliably disable this.
Some applications provide a "paste without formatting" that is distinct from "paste" but often that one removes things like hyperlinks, which you generally want to keep.
The "paste" idiom has been thoroughly stressed to the limit. Should "paste" paste just text? Should it include text color? Should it in crude text background color? Should it include typeface? Should it include text size? Should it include attached metadata like hyperlinks? Should it include other stuff around and peripheral to the text?
