Re: Ingesting progress bar
OK, then if you use the minimize button in the Ingest progress window's title bar, then it will move to the dock. While in the dock, it will show its progress. You can always get to the various Ingest progress windows via the Windows menu.
But no, there is no way to make it float above all other windows as that would likely upset more people than it would make them happy.
You can set its size and position and it will be remembered and restored. So maybe put it off to one side of your contact sheet windows so you can monitor its progress, or use the minimize to dock trick.
