Would be nice to show status per job. For example, display the next/last run dates per job in the table (and maybe interval). The status (RUNNING, PAUSED, DONE) indicates the status of the Quartz service, not that of a particular job (Just that if you add a new OAI feed, it will run at a specific interval. That is all.). That you have to change the status to run a given job it is not clear, nor when the job finishes is there indication if/when that happened. (To determine if a specific job/trigger is running with quartz, we might be able to use Scheduler.getCurrentlyExecutingJobs).

Also, you must specify an interval when creating a job. If you want a job to be manual, you can create a very large interval. Then you'll have to change the status (for all the jobs) to run it. However, you can remove that interval using View and "Delete". Why not allow creating a manual job with no interval to begin with?

Once you View the job and modify it, after confirm Delete, there's no way to return to the OAI page - you have to go all the way back to Admin, then OAI harvest page.
