@noahasm I hope the translation I have is correct :)

* I understand that you dislike the browser in a sidebar instead of in an actual window drawer. I think a drawer is nicer as well, however, it becomes a problem when using MacVim in fullscreen mode. This will be especially noticeable when Lion comes out, which encourages fullscreen usage.

* To get the drawer on the left edge of the window you don't need to change the source, but instead set the preference like so: $ defaults write org.vim.MacVim MMDrawerPreferredEdge 1

Hope this helps :)
