"easy vim", aka evim, or "vim -y". see "man vim"
That said, if modeless editor you are looking for... then vim is not the editor you're looking for. It goes against what vim is, and hamstrings it. Learning vim is a journey, and once comfort sets in, you will understand why, why vim.
Of course, I did have to google how to quit easy vim.
For those who know how to quit vim, but want to experience "how do I quit" again, try running `:term`.
cntrl-o --> to get to normal vim mode
then exit as usual
Not the first, not the last hacky project. Saying that it goes against what it is makes me think of JS V8 being used outside of browser.
Perhaps there are good reasons for not having modeless vim (or server side js for that matter), but the industry overwhelmingly accepts good enough solutions, with good enough results.
Vim go brrrrrr, I guess.
