To expand on this: I use VimWiki daily and it's been a really great way to keep myself organized. Being able to easily hyperlink and jump between documents makes navigating the document hierarchy very straightforward. I have VimWiki set up to integrate with Taskwarrior, so I can create and manage tasks right from Vim and everything gets persisted in a Taskwarrior file, which I can then use to generate reports or otherwise manipulate via standard Taskwarrior commands. Creating/managing tabular data has never been easier in Vim with the help of VimWiki. The list goes on; I really can't sing its praises enough!
