In the free tier
The Command Centre comes with Starter. It is not held back until somebody pays, because you cannot run an intranet you cannot see.
Files, folders, tags, a recycle bin, news, people, accounts, analytics and every setting, in one place that is not the WordPress dashboard.
That person is almost never the one who installed it. So the Command Centre is written in plain words, keeps everything on one screen, and never sends anybody off into the WordPress dashboard to finish a job it started.
Analytics sit in the same screen as everything else, and they are there for one practical purpose: working out whether the document the whole company wants is one tap away or three folders deep with the wrong name on it. Then you move it.
The Command Centre comes with Starter. It is not held back until somebody pays, because you cannot run an intranet you cannot see.
Reorganise the whole library from one screen, and pull anything back out of the recycle bin if the reorganising went badly.
Uploads and moves can be taken back. Filing is done in a hurry, usually while somebody is waiting on the phone.
Invites, departments and who can see what, in the same place as the files those permissions apply to.
Branding, security, departments, news and the rest of it, without hunting through the WordPress menus.
Starter includes the Command Centre. Standard adds the analytics that matter day to day. Premium adds your logo, colours and a choice of 12 fonts, the Spotlight builder with its shareable draft previews, email support from this screen, and the searches that came back with nothing.
Folders that behave like folders, previews in the browser, and a search that reads what is printed inside the documents.
One news feed for everything the company announces, and urgent banners that scroll across every screen and arrive without anyone reloading anything.
A staff directory, invites by email, and a book of the outside numbers everyone keeps losing.
Its own login, download links that expire, and locks checked on the server rather than hidden with CSS.
Install the plugin, run the setup wizard, and the Command Centre is there with everything in it. The file library is free for as long as you want it; you pay when you want the rest.
