The OliveTin web UI is reasonably customizable - parts of the page that you don’t need can be hidden when they’re not needed.
You can choose to hide the navigation elements in OliveTin, to present a simplified user interface.
To have OliveTin hide these buttons, add
showNavigation: false to your config.yaml;
logLevel: "INFO" showNavigation: false actions: ....
You can disable the "new version" information in the footer - the default for
logLevel: "INFO" showNewVersions: false
If disabled, OliveTin will still check for new versions in the background, but will not display them on the page. If you want to disable update checking completely, see disable update checking.
