There are lots of plugins that do similar jobs to those that I'm going to mention, but I'm not interested in making this an exhaustive list; these are my recommendations based on experience, and they may well change as time goes on:

1. Syntax checking/linting
2. File navigation
3. Keyword searching

I know Vim better than most. Vim was my first real text editor. I used it for years. I helped write the Floobits plugin for Vim. I’ve delved into Vim’s source code to figure out its workings. I even helped write a patch (though it was rejected). Considering these credentials, I hope you’ll accept that I know what I’m talking about.

It may come as a shock when I say: The only good part of Vim is its user interface.
