This is a NERDTree plugin that highlights all visible nodes that are open in Vim.
It also maps a key w to close (wipeout) the buffer associated with the current node.
NOTE: This plugin is incompatible withnerdtree-git-pluginandvim-devicons. This plugin causes flags to be completely concealed, while the aforementioned plugins rely on the flags being visible. Don't ask for this to be changed.
