How to delete fixtures from focus palettes

Not sure if this can be done on the actual SFML surface but it can be done in Smartsoft: On the Palettes tab just double click on the PAN and Tilt values of a device you want to remove and delete their values. Once both values are deleted the device will be removed from that Focus Palette. On the surface you can delete ALL Palettes in the Setup menu - but this deletes ALL Focus/Colour/Beam palettes so don't do it unless you want to start from a blank Palette set!!!

Thanks Stix for the help. That makes sense. Still trying to wrap my mind around Smartsoft and what can be done with it.
