The missing up arrow in so many of XP's windows has been replaced by this Breadcrumb joke. The problem is - many of us aren't laughing. I understand the theoretical efficient basis of this crummy idea, but what so many of it's supporters don't seem to realize is the time it takes to find, identify, and verify what parent level you want to go up to before even clicking the mouse! I don't want to have to jump through these hoops just to go up one level.
With the up button it was straight forward and easy. Two levels - click, click. With the crumb bum idea, lets see, what was the name of that level? I can't see it cause the field is too short! Use the keyboard? A lot more work than before. And Why? The button was just fine.
The point is geek boys, that computers should serve us. Changing a tried and true feature for some "maybe this will be better" idea, and not giving the user the choice is typical of the arrogance microsoft is constantly acused of. Considering the fantastic bloat that is Vista, would both a crumb and a button be to much to ask?
