 \*: Vim may be slow if the feature is enabled. Find a balance between syntax highlight and speed. By the way, custom syntax could be added in `~/.vim/syntax` or `$VIM/vimfiles/syntax`.
 
-**Note**: `filetype` used to be set to `javascript.vue`, which caused `javascript` syntax to be loaded multiple times and a significant delay. Now it is `vue` so autocmds and other settings for `javascript` have to be manually enabled for `vue`.

+- `filetype` used to be set to `javascript.vue`, which caused `javascript` syntax to be loaded multiple times and a significant delay. Now it is `vue` so autocmds and other settings for `javascript` have to be manually enabled for `vue`.
+- `g:vim_vue_plugin_use_foldexpr` default value used to be `1`, but there are other foldmethod choices. So it's changed to `0`.
