I stumbled upon a neat little trick where you can use the classic Gnome2 panel with Ubuntu’s new Unity interface. You just need to run 1 simple command.
Press Alt + F2 and run:
For the Gnome 2 panel to load on startup, you need to add it to the startup applications. Open up Startup Applications Preferences by pressing Alt + F2 and running:
or by going to System > Preferences > Startup Applications. (Or from the Unity dash, see video)
Add the command used to load the Gnome2 panel.
You can still view the Unity dash by pressing the Super (Windows) key.
