Is there a way to delete a branch?

I created a branch off my current branch just to try something, and I’d like to throw it away, but can’t seem to find a way to delete it…I switched back to my original branch, but seem to be missing how to delete a branch…?

Dave says: Each branch will be represented by a separate project, so you can go into the project (make sure it’s the one with the right branch name) and delete the project. Note that it takes a little bit of time for the delete to happen and the project to disappear.
