VSys One's developers built the VSys One home screen in a way that is hopefully intuitive and useful for everyone. It looks the same all the time: same tools, same panels, same arrangements. (Tools which are disabled or not permitted by VSys Security don't display.) Want to change how VSys looks? Maybe define more than one layout for different groups of users? That's what tool profiles are for.
Define one or more tool profiles on the Setup panel using the Tool profiles link.
