None. I use vim on so many different machines, so it isn't feasible for me to move a bunch of plugins around. I'll very rarely use BufferList, if it's installed, I often forget it's there.

Here's my .vimrc: http://gist.github.com/517464

I like to use cursorcolumn and cursorline with low contrast colorschemes like obsidian or evening.

I've been using vim for 10-15 years.
