Simple Feature Request: Make zero opacity of Progress Bar actually zero

When I’m building a simple application with fast loading, I turn the progress bar opacity to 0 because it’s a distraction to see a fast colour zip across the top of the screen.

But turning to 0 opacity doesn’t give it 0 opacity. On a white screen you still see a coloured progress bar.

Is this a bug?

  1. Would love to have a) opacity work and b) the ability to fully customise the progress bar at the top of the screen such as turn it off, height, top padding, different colours for when page shows a popup and dark overlay and when in non-popup view.

  2. I was sure that ‘new app released’ blue text on black bar was colour customisable but can’t see that option. Was I dreaming?
