Progress bar unhelpful (and dangerous?)

[dolezvo1]

I've been trying to install a project to my Pharo instance, and I couldn't help but notice the progress bar when using the Metacello install feature. For one, the progress bar is extremely unhelpful, because the rapidly changing width prevents you from actually measuring the progress of installation in time. Additionally, I think the flickering as observed could potentially be dangerous to people suffering from Photosensitive Epilepsy, and therefore should be removed as much as possible.
