Hard Drive location on open screen and File-> recent projects.
I have four production drives, so when I open Sonar it shows me my last session, but I save to two drives after I finish with the song for the day. I'd like to always see the drive location of each version on the File recent projects list, so when I open Sonar so I can quickly choose the version that exists on my RAID drive. A couple times I've found myself mixing and thought my machine was really slow, only to realize I opened the session on the wrong drive.
