Clicking the delete button in VSB is way too easy to do on accident.  When clicked, the repo is deleted without a prompt and without the ability to undo.  The delete button is quite big and I've already accidentally deleted a few Repo's.  See attached screenshot.  

Feature request is one or both of the following:
- Add a "Are you sure?" prompt when clicking the button
- Add ability to use Undo to un-delete the repo.

In addition to that, it may be nice to make the delete button smaller.
