Step7: Adding a system tray docklet is very simple actually. right click somewhere on the dock and again go to  ADD item > KK menu , just as you  did the first time. Then RIGHT click the empty spot and rather than adding an image this time DONT!  Just click Setup tray and in the window that just popd up check the first box ENABLE ! and thats it ! now i increase the first number under enable to 50 so all my tray icons can fit. but whatever you want you DONT need to change it ! and i suggest you dont !!  
- That's it just close and close !! you should have a tray.  
 
Step8: After setting up your menu you might have noticed that it is small !  and NOT LOONG enough to fit atleast a good dozen of folders, so to increase the size  just simply right click the menu icon again and go toothe KK menu setup , and change the MAX height to 80 ( that's what i have and it works fine ! ) play around with that and see what height suits you !
