Woah! I had no idea about the "application" feature of Chrome! That is so simple, yet so ingenious!
Try this:
Go to Gmail, then when it's loaded, in the top right in Chrome go to Page -> Create App Shortcut and choose a location (say the Desktop). Then go to the location, and "open" the application. It's like an actual Windows app!
Safari has had the "drag tab for a new window" feature for a few years, and Apple hasn't had any problems... yet. Of course I doubt Adobe would want to mess with Apple, or Google for that matter.
Just the way these things go - the same happened with features from Opera being introduced to a wider audience through Firefox. Answer: if you want credit for an idea, implement and get it in the hands of millions of people.
Sorry, not impressed. A desktop shortcut to Gmail with no address bar or buttons doesn't exactly 'wow' me. I still have to login, and I have enough screen real estate that I would prefer to have those buttons/toolbars available.
It's sorta funny because in the past people complained about sites hiding browser chrome and rejoiced when browsers let you disable that Javascript feature; now it's reversed and we're excited to be able to view sites without browser chrome.
When sites hide chrome, it's bad. When apps do it, it's good. The obvious difference is that (most) webapps don't use the browser chrome e for anything anyway, so removing it just makes the design less confusing and cluttered. Not to say that apps shouldn't make the chrome work for them....
