"Show Disks Window" alway staying in front... but optinal.

[TheVento]

This is a feature request, rather than a bug... But still an issue.
I like to have the "Disks Window" open all the time when working with external devices, but the behavior of this window always staying on top of everything (even when using another App in fullscreen, and/or even being present on EVERY desktop when using multiple desktops/spaces) is annoying. What about making it an option, changeable in the preferences, to decide wether the "Disks Window" shall be floating on top always or just behave like any other window?
