Why do I love Google Chrome so much, and want it to come out for mac already? Because instead of making a new version of old technology they tried to rethink the browser at every level.
Obama said that single-payer healthcare would be great if we were starting from scratch, but we’re not starting from scratch; we’ve got a huge and decentralized healthcare system with many interested, powerful, and wealthy parties all along the ideological/evilness spectrum and starting from scratch is simply politically infeasible (i.e., not possible according to the rules of the world in which we live, as cold fusion and perpetual motion).
But whereas reforming healthcare requires incorporating programs and systems that have been in place since Harry S Truman (one instance where I disagree with the CMOS), internet browsers are much less burdened by legacy issues. In particular, while support for previous standards for HTML, JavaScript, etc., most of the front-of-the-house stuff that users actually see and use is constrained only by the habits and tendencies of, as the French deem them, internautes. So Google started from scratch.
Example: A tab is not just a taskbar-button type thing moved from the bottom of the screen to the top of the screen. An analogy: looking for a definition of an unknown word, I reach for the dictionary. This is like opening a program, or an instance of a program; I have a question to answer or task to accomplish (i.e., defining a word) and so open something to answer that question or accomplish that task. But if I’m looking for word to express a particular idea, I reach for the thesaurus. Perhaps I find the word right away, but perhaps I go to one entry, follow a cross reference to another, etc. It’s a process of digression from a starting point. This is a tab: a node of a network, connecting to other nodes and leading to a destination that may be far from where I began.
The point: tabs are connected, and should open next to each other. If I want to take one and start exploring off from that starting node, I can drag it off the tab bar and make it a window. I know very little about design, but I know this: form should follow function. For a sculpture, book, etc., form that’s unrelated to function is fine, but design is the art of function.
Tabs not resizing while closing them, so you can rapid-fire kill them; unifying search bar and address bar; plus-button to add tabs on the right; hiding the toolbar behind pull-down buttons; using the critical space normally taken up with the title bar, even though it’s utterly obvious which window is open (I think this is a hold over from pre-task bar days, when you could maximize a Windows 3.11 window and not necessarily know which program was selected; also, one of the few things I think works better in current Windows than Mac OSX). Small things, all of them.
But not really.
