Neovim is mostly backward compatible with Vim, and supports a huge number of Vim plugins (in fact, Neovim supports every plugin listed in this book except for Powerline).

All of the following plugins (except for NyaoVim) were backported to Vim, but it's worth giving the Neovim community credit for the crea
