Show SubPanels in Tabs?

Been trying to find a way to do this, how would one make it so some of the subpanels on detail view,
rather than being one under another in Accordions,
are shown as tabs?

So, a random e.g, having the main of Contacts on the first tab, the More Details as another tab, and the Related Accounts in another.

this is a mockup made using Chrome Inspector from editing a module which already makes use of tabs though not for the subpanels.

each user has the option to show Subpanel as Tabs, User -> Advanced -> Subpanel Tabs

Then you need to play around with Admin -> Configure Module Menu Filters to achieve how you want it.

The way you want it is not an easy and upgrade safe task
