Our tab manager lets you pick, organise and re-name your group navigation tabs. Go to 'Tabs' under the 'Website' tab to find this.
From here you can drag & drop available tabs into the current tab list on the left, drag & drop current tabs into your prefered position to change the order they display in (higher to move them left, lower to move them right) and use the pencil icon to rename or red cross to delete the tab.
'Pages' you create and then remove the tab for will still be available to add again in the future. Deleting a tab doesn't turn off the feature or delete the page, so make sure you also check the relevant settings pages when you add and remove tabs.
Remember to click 'Save Changes' when you've finished!
