Add Window List or Window Selector to Gnome Panel

1. If you don't have any panel you need to press Alt+F2 and type on the appearing window: gnome-panel
2. If you still have a panel just click with right button of mouse and choose 'New Panel'
3. When you have a panel, right click it, choose 'Add to panel' and add a 'Window List' or a 'Window Selector'. Window List is what you had before, and a Window Selector is a button that shows your windows when you click on it.
