VIM Plugins - What's Your Favorite Plugin?

VIM is so extensible you can literally find extensions to search through anything you want and that would probably be the most used one simply because you drop into a code base or a document and you can easily find where you want to get to really quickly. There's a open source library called RipGrep and that's the cross platform so it probably is the same not just windows but I've used that for quite a while. It does use RipGrep under the hood and it's really fast as it's set yeah.
