I rearranged the panels to have only one panel at the bottom and added buttons for firefox, terminal, tomboy and deskbar. I guess that comes from the many years of using windows. Also, I like to have menus and buttons in one place, and since this is quite a wide screen, it doesn’t make sense wasting horizontal space. I found having only a top panel weird looking. It results in two bars across the whole top of the screen when a window is maximised – does not look good to me.
After moving everything to the bottom, I noticed that the menus seem to be arranged with a top panel in mind. Need to investigate reordering menus later, maybe look at SUSE’s menu.
Oh, I also tried to play an MP3 file. As expected it did not work. Will deal with restricted formats later.
