@feudjais as a new user, I figure that using 'source' and using many individual vim files focused on one specific thing is very unix-y
Like I got a file dedicated only to nerdtree and its associated plugins. So if I wanna add nerdtree the way I want it, I just add that file.
And if I wanna add autocomplete and programming language support, that's it's own file as well.
Also: nerdtree is good
