Very often, I mix Java/SQL/XML code and I'd like to help Code Prettify to assess what type of code I'm writing, as it's not good in guessing mixed code. I didn't even know until asking this question, that it actually doesn't guess, but the Stack Overflow tags indicate the language. Also, I think many users don't know there is such a prettify language hinting feature.
And I keep forgetting how it works, as this is entirely different on every forum/blog software. So I have to look it up. Check out the number of required steps:
Step 1 - The obvious one
Step 2 - OK, I see. This step saves some space
Step 3 - Why is Code Prettify info missing here?
Step 4 - If I haven't lost attention yet... Scroll to the bottom
Step 5 - Another expand button
I think this information deserves more importance, at least to hint that such a thing exists. I'd put it in step 3
