I disagree. If you don't want your email to look the way Gmail displays it, use a different client. I don't want a million configurations for how I could possibly have my mail displayed. Show me a good option. If I don't like it, I'll use a different option. That being said, one thing I really miss in Gmail compared to other options is being able to do things like sort by the sender and that sort of thing. Instead I have to search for that sender which often gives me many false positives.
