title: How do I add or remove plugins in CKEditor without rebuilding?
body: <p>I've just started using CKEditor 4 (having previously used version 1 a long time ago). I like that I can build it online and download it, but when I do that, I then use the toolbar config tool to set up my toolbar.</p>
  
  <p>What happens if I want to add or remove a specific plugin in future though? Will I have to build a completely new CKEditor using the build tool, then download it to replace the existing one, and then reconfigure my toolbar? I don't really want to have to reconfig the toolbar each time.</p>
  
  <p>There are a couple of plugins that I might want to use later, so I'm just trying to figure out whether I need to include them now, or can I add them in with no hassle later on?</p>
