since I have a 13" screen and generally dislike clutter, I used this upper-right small button a lot.. Seems to have disappeared in Lion. What it's called? And is there a way to bring back its functionality?
Finally, back to SL. Now, I find it would have been nice to get "The Pill" in Safari.
If you miss it also, don't forget to send your feedback to Apple, there: http://www.apple.com/feedback
They never answer, but surely read everything. I'm pretty sure it helps a lot when you're being polite and write without too many mistakes.
Yeah, I don't see what the big deal here is. Screens are getting larger and I would venture that this feature was rarely used anyways. Plus with most applications you could always go full screen.
You could also just hide the toolbar instead and regain space that way (at least in Safari). Navigate using the Command-L shortcut.
Switching from a 13" to another 13" didn't make it any larger. Resolution is still the same 1280x800.
I actually hate full screen as it is an inefficient use of the available estate. Much better is the "optimal fit" for maximum visibility yet leave room for other applications to share. I found pre-Lion versions excellent in this regard.
