How do I see a list of Git-created reviews?

You can view all reviews that were initiated in Git. First, you need to fetch any review branches that may exist: 

$ git fetch --prune origin

Then you can list all branches, which includes any review branches, for the current Git Fusion repo: 

$ git branch -a
  task1
* master
  remotes/origin/task1
  remotes/origin/master
  remotes/origin/review/task1/1234
  remotes/origin/review/task1/1244
  remotes/origin/review/task1/1347
  remotes/origin/review/master/1235
  remotes/origin/review/master/1236
  remotes/origin/review/master/1358

Note

Git users cannot see Swarm reviews initiated in Perforce.
