Add "Confirm Delete" When Deleting Tab Groups

[KamiSamaFreak]

As title above.

Deleted a group with 12 tabs accidentally, was a big headache to regain the lost tabs.
Alternatively add a Undo close tab group feature.

In addition any form of backup would be fantastic.

Thank you for your time and promise to donate 30~$ if/when this gets implemented.
