One of the reasons why I'm sticking with Yosemite for however long necessary as I can continue using TotalFinder (or XtraFinder).
What Apple has done to the Finder with El Capitan and third party developers is a disgusting slap to the face of everyone. I get that some people PREFER things differently but my god, make it OPTIONAL in system preferences at least!
Yeah, Apple is hitting their experienced users hard. Steve would not have allowed this. Cook is all about targeting new customers and making even larger profits, so he wants to make sure that the OS is more inviting. He's also responsible low-end Macs turning into complete crap. I know Steve was a business man, but he put his heart into the company and wasn't materialistic. He wouldn't have made such compromises in order to maximize profits.
