Comment 11 for bug 880331

Those are valid points, we dislike some of things GNOME3 did (like dropping support for custom screensaver graphics), some will be added back, GNOME3 and Unity are still quite new, I understand it can be frustrating meanwhile, sorry about that.

Some side notes on the example you took
- you can change the default session simply by picking it in lightdm (you need to log you and log in with the news session), but indeed it might not be obvious for users who configured autologin and usually don't see the login screen.
- user groups configuration is a "known issue", you can only deal with profiles in the new UI, you can look at bug #840682 if you are interested in that issue or https://bugzilla.gnome.org/show_bug.cgi?id=658418
- not sure that the power button configurability is something useful, it displays a dialog with the different sessions option, which is something that works for 99% of the users, the extra 1% can still get to the setting with tweak tools
