no-neck-pain.nvim is a Neovim plugin that centers the focused buffer in the middle of the screen by creating empty side buffers. It provides a non-opinionated, highly configurable zen-like editing experience without the intrusive UI changes typical of other 'distraction-free' plugins. The plugin manages window layout across multiple tabs, supports splits/vsplits, and integrates with popular file trees (NvimTree, Neo-tree), dashboards (alpha, snacks), and other tools like undotree, neotest, nvim-dap-ui, outline, and aerial. The architecture is modular Lua with clear separation into configuration, state management, UI creation, color handling, and utility modules. The core logic revolves around dynamic layout scanning via Neovim's winlayout API, event-driven re-initialization, and per-tab state tracking.
quicker.nvim is a Neovim plugin that replaces the default quickfix and location list windows with an enhanced, feature-rich interface. It provides improved styling with syntax highlighting (treesitter and LSP), context line expansion around matched results, and an editable quickfix buffer that allows applying bulk text changes across multiple source files on save. The plugin is implemented as a single modular Lua library using Neovim's `quickfixtextfunc` hook for rendering and leverages async processing for highlighting performance. It includes a suite of helper APIs for toggling, opening, closing, refreshing, and configuring the quickfix window. The codebase is well-structured, thoroughly tested, and actively maintained by a prolific Neovim plugin author.
