Haven't really looked at the source, but is the neovim dependence just for starting ranger async? In that case vim 8 support might come soon?

I have a neovim build, but I tried out SpaceVim on it and just went back to a very lightly patched vim since SpaceVim felt too bloated and I've been too lazy to clean it all up.

This is a "neovim" storage explorer plugin to bring together the best of Vim, ranger, and rclone. It's called vim-netranger just because I might port it to vim8 in the future. It's still under development, but is already very useful.
