Uipress comes with the option to white label itself and WordPress. One feature that allows you to keep your users away from knowing you are using UiPress is the option to hide it in the plugins table.
To do this, go to settings > uipress settings and click the general tab.
Once enabled, uipress will not show to any user in the plugin table. If you need to deactivate uipress you can just disable this option and it will show again.
