lightline.vim
A light and configurable statusline/tabline plugin for Vim
...Importantly, the plugin is designed to be minimal and orthogonal—i.e., it doesn’t impose or depend on other plugins, but offers a clean API so you can integrate other tools. Many users adopt Lightline for both aesthetic and functional improvements (e.g., cleaner statusline, better separation of mode/filename/flags, consistent look across color schemes). Because it's lightweight, it typically has minimal performance impact.
