I recently came across a two awesome file/buffer utilities for vim. Unfortunately all of them were blocked due to a ruby/vim interop issue which recently got patched. Thanks to Matt and Bram for including it in the official branch.
Update: Removed links to my drop of gvim to avoid duplicacy. Wu Yongwei maintains a regularly updated patched version of gvim drop.You can get version 7.3.89 with the above mentioned patches from here.
The package contains gvim.exe and vim.exe, backup and replace these binaries in your existing vim73 install.
