This is a real flaw in the product (almost a bug), you cannot search for a schedule. We have about 150 jobs scheduled to run daily. If you want to amend the schedule you have to page next through all the schedules to find it. If you search for the workflow name, you get the workflow screen which does not contain a link to the schedules.
Also add a link to the schedules for each job on the workflow page. I.e. search for job ABC, see that it has 3 different schedules associated with it and be able to edit, or delete any of its schedules.
