Oftentimes I'll want to put remaps in my `.vimrc` that use plugin commands. When a plugin happens to not be installed, these remaps will result in errors. A simple workaround would be to put an if-statement around plugin-specific remaps that checks whether that plugin has been activated.

How can I do this with VimPlug? Does VimPlug store a list somewhere?

----
**Edit**, to clarify things: I need an actual list or a string, not the panel that `:PlugStatus` brings up. For example: with [a list](http://learnvimscriptthehardway.stevelosh.com/chapters/35.html) of activated plugins, any remaps specific to the plugin `plugin_name` would be wrapped in this if statement: 

```vim
if index(plugin_list, 'plugin_name') != -1
  <special remaps here>
endif
```

The `index` command returns `-1` if the string `'plugin_name'` is not contained in the list `plugin_list`.
