Is there a way to add CKEditor plugins?

[FollowSteph]

For example I'd like to install this plugin but can't seem to find any way to do so...

Well, this should work:

CKEditorConfig ckEditorConfig = new CKEditorConfig();
ckEditorConfig.addToExtraPlugins(<plugin-name>");

But this add-on seems to try pulling extra plugins from non-existing URL's. such as http://cdn.ckeditor.com/4.6.2/standard/plugins/font/plugin.js

For extra plugins there should be standard-all in the address, eg.:
http://cdn.ckeditor.com/4.6.2/standard-all/plugins/font/plugin.js

I found a workaround.
First, download the plugin and put all files (i.e. plugin folder) somewhere under webapp
Before the code above, i.e. before CKEditorConfig instantiation add following:

JavaScript.getCurrent().execute("CKEDITOR.plugins.addExternal( '<plugin-name>', '<path-to-plugin-folder', 'plugin.js' );");

Note that path-to-plugin-folder must be absolute (start with a slash), but in client context, i.e. relative to webapp
