Quick Launch Tab

In Kinetic when you first log in on the home screen is a Quick Launch tab. I know you can edit tab and remove it or remove items. Is there a way to just hide that tab from everyone? I am wondering if it can be hidden. Since when you edit it you can check a box to Retain When Hidden. Unless I don’t understand this properly.

Can I also create Tabs (pages; I am not sure of the correct terminology) for specific users. So I would like to create one for Purchasing. I know I can create a new tab just not sure if I can publish it for all users.
