Among the editors and IDEs that I use the old stand by vim is always there. It's literally the first thing I install on a server. One of the great features of vim is the vast plugin library. This becomes even better when someone wraps a lot of the extremely useful ones in to an installable package.
Enter SPF13 vim by Steve Francia.
It has my favorite plugin NERDTree plus a ton of others that I didn't know I loved until I installed this package.
This is an awesome vim setup!
One word of warning vim needs to be 7.4+ for the plugins installed with the installer to work.
