I have a webapp with list of background jobs (interface is similar to this template). It displays progress bar on each job. Queued jobs have indeterminate style, running have some percentage and completed are always 100%. Also each job has a badge on the right that indicates it's status.
Now should I hide progress bar when job is complete since it delivers no useful information? I tend to leave indeterminate bars for queued jobs in place to assure users that job will be processed when some background workers become available.
