Advanced test plan structure in Jmeter

Working with JMeter for about 2 years I've come to the optimal (for me) structure of the test plan. It's divided into several suites (thread groups) depending on user type (visitor or signed in user, etc.) and is quite large to simulate real user activity. Complex business operations can be grouped using Simple Controller for better readability of the test plan. Also do not forget about pauses.

Here is an example test plan structure:
Thread Group - Visitor Suite
  Simple Controller - Homepage
    Transaction Controller - Homepage
      HTTP Request Sampler
      ...
  Random Order Controller
    Simple Controller - News page
      Transaction Controller - News page
        HTTP Request Sampler
        ...
    ...
Thread Group - User Suite

  Simple Controller - Sign In page
    Transaction Controller - Sign In page
      HTTP Request Sampler
      ...
  Random Order Controller
    Simple Controller - View User Profile page
      Transaction Controller - View User Profile page
        HTTP Request Sampler
        ...
