Dolphin immediately useful
Like many, I read this already famous blog post about the stripped-down Nautilus with growing surprise. I won't go into what I think it's wrong with it as others have said enough already. I'd like to focus on the positive: the very first point made.
Mccan describes how Nautilus should be immediately useful upon starting. This is accomplished by showing recent files instead of the home folder of the user. A very neath idea, actually - I always have all my files sorted on date (newest on top) and most of the time that means I just have to click on the top-left of the file view in a folder to get what I want. But I first have to go to the right folder... So I'd say - awesome idea.
