Idea: autocomplete for various parts of commands

It would be absolutely awesome if autocomplete was added for file/column names. E.g. when having single file open with long name it is cumbersome to type it manually therefore just typing :S FROM <tab> will inject currently open file name. Maybe could be easier solved with some pre-defined vars, like $1, but that would seems less discoverable to me.

Just found this project from the Reddit post the other day. Working with data it's what I've been looking for but autocomplete would really make it awesome.
