This Neovim plugin provides a floating window for entering ex-commands, featuring tab completion, history navigation (with optional smart history), and customizable keybindings. It is built on top of the nui.nvim library and offers a clean API for configuration and extension via hooks. The plugin handles compatibility across different Neovim versions (pre and post 0.7) for keymap settings. The implementation is focused and modular, separating concerns between UI setup, state management, and user interaction.
