Easily recognize comment threads via consistent visual indentation

I received an email that /comments/1128 was created in response to /comments/1099

However, when I visit /problems/30 , I notice that these two comments appear at the same horizontal indentation, so visually it appears to me as if they were both made as responses to the original problem rather than one as a response to the other.

I have seen comment replies sometimes indented but not consistently. Could comment replies be indented consistently for easier understanding? Thanks!
