Window Applets is a pack of two GNOME panel applets that lets you put the window title and buttons on the top panel. Since GNOME 3, Window Applets stopped working but today, a new version has been released with support for the GNOME 3 classic / fallback panel.
The Window Buttons applet is basically like the Ubuntu window buttons displayed on the top panel for maximized windows, except it's for the classic GNOME session and it's highly customizable:
- you can move it anywhere you want on the panel
- many built-in themes, more available on Gnome-Look.org
- select if you want it to control all windows or only maximized windows
- automatically hide for non-maximized windows
- change the button order
- hide some of the buttons
- more!
Dmitry Shachnev has written a small guide to get a fully working classic GNOME session in Ubuntu 11.10 Oneiric Ocelot, similar to Ubuntu 11.04 Natty Narwhal.
The guide includes: use the GTK3 indicator applet instead of the standard systray, fix the panel background for Ambiance, get Compiz to work and use the Ubuntu logo in the applications menu applet.
Jason Conti has ported Indicator Applet to GNOME 3. That means that you can now get almost the same classic (fall-back) GNOME 3 session look in Ubuntu 11.10 like in Ubuntu 11.04.
With this, you'll be able to use all the applications that come with an Ubuntu Appindicator, Indicator Date/Time, the session indicator, network, Ubuntu Sound Menu, Messaging Menu and even the Global Menu (optional) in the classic (fallback) GNOME 3 session, just like in Unity. However, unlike in Unity, the Global Menu doesn't hide automatically for maximized windows and there are no buttons on the top panel.
Here is a video (includes the applets you need to remove and add to the panel to get an Ubuntu 11.04-like look) demoing the GNOME 3 Indicator Applet running in Ubuntu 11.10 Oneiric Ocelot (classic session):
