I have written elsewhere about the lack of information about the progress panel.
What function does this panel have? What features can a user expect to find here? How can a user interact with this panel? What is the expected behaviour?
The Progress panel shows when an autosave in the background is happening, clips in the project panel are transcribing, enhance speech progress, linking media and much more. You have the ability to dock this panel to your workspace to see it happen or click on the 3 horizontal rounded rectangles in the upper right hand corner of the UI.
