I have this hints:
1- Look at bottons near left side of screen, use it to floating panel mode, and you can do all tasks from map panel, look at attachment
2- In matchBox, use CTRL+ALT+LEFT or CTRL+ALT+RIGHT to change virtual desktop, the others desktops dont have the task bar
3- Use map panel in maximized mod and all others in floating mode, in desktop 2 (or high) without task bar, you can use the bar vacuum to move in others panels.... I think this is a good way to play... I have played a match in a metaserver, yeap its nice....
