( ^ This is for the SFDC version)
Unable to rearange groups in Administration / Cockpit / CTA / Detail view layout configuration / CTA tab without removing and readding everything.
Usecase: someone requested we add another group at the beginning of the CTA type and we have 13 groups already present.
There is no way to shift the newly added one to the top. (attached , you can see the UI buttons available in the right side which point to delete + fold/collapse group)
