Build a Playlist Manager with add, remove, and favorites in egui! In this episode, we combine text inputs, buttons, checkboxes, scroll area, and Vec state into a complete CRUD app — all coded in Neovim. Student code: https://github.com/GoCelesteAI/egui_playlist_manager What You'll Learn: - Vec for managing playlist state - TextEdit::singleline with add_sized for fixed-width inputs - add_enabled() to disable buttons until fields are filled - ScrollArea::vertical() for scrollable song lists - RichText::new().strong() for bold labels - Layout::right_to_left() for right-aligned remove buttons - Deferred removal with Option to avoid borrow conflicts - Neo-tree — natural project navigation This is Episode 27 of the "Learn egui in Neovim" series where we build real desktop apps with Rust's egui framework, all coded in Neovim with Neo-tree.
