Reboot after that the max/min buttons return to the application windows like it was.This is the first thing I do when I install Ubuntu.sudo apt-get remove indicator-appmenu
If you like point and click the gnome2 way you can simply install a classic menu, you even have two choices.
If you want the tray icons back, install dconf-tools, invoke the dconf-editor with alt+f2 (or use the classic menu thingy if you prefer) the command is simply "dconf-editor" (without quotes), go to desktop > Unity > panel and change the systray whitlist to ['all'] (with the brackets and quotations)
Now you can even move the Unity launcher bar to the bottom
So all your problems are solved.
Now in 11.10 a lot of options are removed but that is the fault of gnome3, not Unity. Actually Canonical seems to have restore some of those features. You don't find them in Fedora's version of gnome shell (not without more work anyway)
