To get just a system create a step.rc file with a LoadModule line for systray2 and include all of the appropriate settings that you need for your layout. I will tell you however you are going to want just more than a tray. Probably a popup, which will require a desktop module, and then to get the show and hide stuff you either need a hotspot module or a shortcut. As for transparent windows...its not an LS function but it can be done with apps like apptrans.
