I think that the autocomplete story is abysmal. Modern IDEs can tell me exactly what can follow after a certain piece of text, and even the best tab completion in terminals is limited, ugly, and text-mode for no good reason.
Some protocol for a real dropdown rendered in the style of the OS, plus a standard data format that allows tool builders to specify options, their meanings and the kinds of allowed parameters in a structural way (much like doccomments in code), is direly needed.
If I type "git " I want to see "add" as an option, with docs in a tooltip as I navigate the options. When I "git add " I want to see a list of files that make sense to add, eg only files that can be staged right now.
I want this to be consistent across commands, I want any shell to be able to add support for this and I want any command line program to be able to add support for this.
