I have been meaning to post this for quite some time, but there is this fantastic website called Vim Awesome that has an exhaustive list of vim plugins along with their respective docs and installation instructions. It is a great way to learn more about all of the wonderful plugins that take vim to the next level.
Vim is awesome in its very own right, but it is powerful plugins like Vim Fugitive that really make it shine in my opinion.
If you are new to vim, or even a veteran who has never really messed around with plugins, I would highly recommend checking out this great resource. As a side note, I would also recommend using Vundle since it makes managing your vim plugins across multiple machines super simple.
