I finally have a vim setup I’m happy with.

The sidebar on the left is NERDtree, the tiny buffer on the top is Lookupfile where I use the :LUWalk command to quickly get to files. The Lookupfile’s default search mode is much like Textmate’s Command-T functionality, but requires the use of generating a ctags file or some such. I might look into it when I get a chance, but I’m happy with the functionality now.

In addition to those plugins, I’ve also mapped F9 and F10 to :bn<CR> and :bp<CR>, respectively, so I can switch rapidly between buffers I have open. There are some issues with what the plugins do if I close all buffers, but I’m sure I’ll sort those things out eventually.
