As I see it, they just want you to Cmd-W. Close the window and the programme is open in the background but using minimal resources.
I've not used Lion yet, but I assume you can Cmd-Q from full screen too?
This still takes two commands rather than one at the moment though, I'd expect some refinment as Lion has point increments.
Yes you can Q from Fullscreen as well.
Lion needs a lot of refining tbh imo.
- Fullscreen moves the App Window to a new Space, so now you can't CMD-<Insert Number> to get to a specific Space anymore.
- There's the issue here with Resume, and the issue where Resume automatically re-opens all Applications after an Emergency Shut Down (Options Box please? When using and Older Computer this can be deadly.....)
- Versions is a Time Machine on Wheels that saves everything. Every time you make even a tiny Spelling Correction, anything at all, it saves it. This is just pointless.
Apart from that, people still using the old Magic Mouse most likely have a clogged Scroll Wheel, with the new Window Re-Size from all Sides feature, those Users need to push the right side of the screen right to the edge of the Scroll Wheel.
And Finder (all Apps tbh...) still don't remember window position and sizing, need to re-size every-single-window, still.
With Resume and the Spaces change, they seem to be throwing in the new stuff, disregarding the old stuff that they've still left coded in, and simply expect us to adapt. The Spaces change, you can still CMD+Numbers to switch Spaces, but not if you use Fullscreen. If you don't want Resume to re-open everything, you need to Close + Quit if you're an Apple-Tab Fast-App Switching User.
I personally don't care how they want me to use the OS (never wanted iOS integration in the first place), if the Apple-Tab Function for Fast-App Switching continues to be a part of Lion, I'll keep using it. Not very nice of them to just trundle on and leave all these gaps in their thinking.
