Feature: Please add "U" to undo all changes on the current line #225
Description
One basic operation I struggle to be without is the U operator to undo all changes on the current line. Can that be added? That operator exists in all other vi/vim emulators I know of and was in vi when I started using it from 1987.
E.g. at least vi, vim, neovim and the vi emulations in VS Code, Pycharm, Zed and bash/readline all have this. I doubt there is any other vi implementation that does not have it.
