There are 2 repositories under fzy topic.
Fuzzy picker & vim.ui.select implementation via fzy for neovim
fuzzy data selection and copy-paste from password store
Search for text in multiple folders simultaneously.
Fuzzy-select buffers, args, tags, help tags, oldfiles and marks using fzy in a terminal window
Feature selection via intuitionistic fuzzy sets
Fuzzy-select files under a specified directory using fzy and your favorite file-searcher (Vim-only)
NOT SUPPORTED. I'm not interested in neovim anymore.
