CaptionHub includes status icons, to show a project's progress at a glance. They're found at the bottom right of thumbnails, and also in the project list view.
The caption progress indicator has a number, as well as filling up. In the example above, there are three sets of captions (an original, and two translations). The box is solid because every single caption has been completed.
The approval progress indicator shows which captions have been approved. In the example above, one of the three language versions have been approved.
