fzf-preview.vim

fzf-preview is a coc extensions and Neovim plugin that provides collection of features to assist file management using fzf. It provides multiple presets of fzf and correspondingly powerful preview. It also provides advanced interactive git integration.

Remote Plugin only works with Neovim, but you can use coc extensions also works in Vim.

This plugin can be easily extended in comparison to fzf.vim.

Search from file history files using oldfiles and mru
Interactive git integration (with Fugitive or Gina)
Jump lines from jumplist or changelist
Interactive grep and preview from the current project
Export the selected items to QuickFix.
