This has been asked before and nothing was done yet.... BUT....

There is one way to check dev posts within a thread.

  1. Open the thread with dev/rep post
  2. On top right of the thread there is "Display" click it
  3. Switch to "Hybrid Mode"
  4. You will see dev/rep posts in red on top of the list - click to view the post.
That's the only method I found so far, hope it helps
