Show/Hide Drives multiple at the same time

It would be nice (instead of just showing one drive at a time and switching between them by dropdown list) if when you first boot the LiveCD that all the drives are showing all at the same time.  There should be a "show/hide" column to the left of the drives where you could uncheck the drive and it would collapse to just the drive's designation, no longer showing the drive map. 

This would especially make selecting a drive easier (by just clicking on it) and doing copy and paste of partitions between drives.

(sorry if this has been requested before, searching didn't locate previous request)
