VimR has full Vim inside. This means for instance that you can use all your favorite plugins. Have an overview over your files. The file browser of VimR offers NERDTree inspired keyboard bindings, e.g. hjkl and more. Open files blazingly fast via Open Quickly a la Xcode. (or Go to File a la TextMate). VimR is extensible via plugins, e.g. for previewing various file formats. Markdown preview is included and more coming.
