...One of its core ideas is lazy loading: you can defer plugin initialization until a command, mapping, filetype, or event is triggered, which helps keep startup fast even with many plugins. NeoBundle also understands plugin dependencies and post-update hooks, allowing complex setups to be reproduced reliably across machines. It supports version pinning and branch selection so teams can stabilize on known-good revisions. Although Shougo later introduced dein.vim as the modern successor, NeoBundle remains a usable, declarative way to manage plugins on classic Vim setups.
