Protect branches from deleting

Hi @sanemat,

I don't know if this feature is off the concept of this extension. I and my team sometimes accidently delete production branch after the branch is merged to master. I know a restore button appears after you remove a branch, but it's not good to delete important branches even in 3 seconds.
So, is it possible to merge this feature? If not, that's totally fine. I should make another extension!


Thanks.
