Sometimes we may want to "clear the table" temporarily from extra tools and data: for example when we need to see the full spectrum (all the carriers) or clearing up things for creating presentation graphics. Special cleanup function can be used for this in two modes: CLEAR and SUPERCLEAR.
Clicking TOOLBAR > CLEAR toggles CLEAR mode on/off and right clicking TOOLBAR > CLEAR toggles SUPERCLEAR on/off.
CLEAR makes "some cleaning" (for example APPLETS, SPECTOR sight and SPECTOR flag and cleaned) but SUPERCLEAR wipes out everything away and leaves only the WALLPAPER and the PLAYBAR visible.
