I really could not disagree with you more.
At any given time i have 3-4 iTerm2 windows open to which if someone closed i would freak and slap them silly. But just because i use the terminal does not mean i don't want a competent file browser.
Im not against there dumbed down version, but Finder as it stands simply isnt practical for a developer, and no i don't want to jump into a terminal to do basic tasks that developer would need to do every day.
