panel problem solved

intro
since last few weeks, i removed my bottom panel to fully utilize the all-beautiful Avant Windows Manager. but now i added the panel back in place
however..

problem
by default, the newly added panel is empty. i'm familiar with workspace switcher and many other panel plugins but doesn't seem to have any idea on this tiny boxes, not even the name. (must be another jargon, urghh)

solution
1) right click on the panel
2) add to panel
3) add the Window List (Switch between open windows using button)

conclusion
don't fancy problems?
do nothing, at all.
