I can name only one thing that has been massively popularised since then in "professional" tools and which I wouldn't mind the older software had: command palette.

Press some hot key, and then type the name of your command in a pop up window with full-text search, autocomplete and a hint what the hot key and toolbar icon for that particular command is. Probably single most useful thing that became mainstream roughly after the ubiquitous CLI-phobia mostly went away.
