Yahoo mail thinks I'm a total moron.?

What a surprise to turn on my computer today and find Yahoo mail changed it up by telling me what emails I received today, yesterday, last week and, last month etc. What the heck yahoo, don't you think I can look down the left side of the page and see the dates? Now it's using up even more room and I get to page down more to look through past emails. For people that are real morons and need this redundancy yeah for the rest of us, give us the option to get rid of this pedantic idea.
