When it comes to cancelling a running/queued job though the Gallery admin portal it never fails to add some new jobs to the list right as I am about to click to cancel a job,
thus instead of removing the unnecessary queued job I actually cancel the job that has been running for the past hour creating the report I need for the meeting in 30 minutes
I think that adding check boxes (similar to the "Users" page) would be a nice UI enhancement to this page
