No indication of how long unpacking archives will take.

When unpacking an archive (tar, zip,etc.) using the "right click --> Extract here" option (which I assume is calling file roller), a window comes up to show that the archive is being unpacked, but the progress bar just goes back and forth until the unpacking is finished. The bar does not fill up, nor is there any kind of time estimate shown for how long it will take to unpack. Nearly every other archiving/unpacking program I have used normally gives some kind of guess as to the time remaining. This is particularly nice when unpacking large archives, which might take a long time.
