I would like to suggest that several rows (instead of just one row) is used for showing the Endpoint, Resource and Parameters which would make viewing a test a little less awkward. Also I notice that trying to amend parameters seems a little clunky, clicking into the fields seems not to be reliable to amend an existing parameter and when the parameter edit window opens it doesn't permit resizing which makes viewing the parameters a little awkward.
