For those of us with two monitors it would be very nice to have the contact sheet open in one monitor and and preview window in another and be able to navigate in the preview window by clicking on the contact sheet. Right now, the preview window is modal so the contact sheet is not accessible. In this two monitor configuration, the filmstrip in the preview window would not be necessary. This kind of setup would make navigation easier.
A minor two monitor annoyance with the current version of PM is that if you have the contact sheet open in on one monitor, the preview window open in the other monitor, and you open another app (typically your editor) that covers up the preview window, I always find myself clicking on the contact sheet to activate PM, but this doesn't work. You either have to minimize the app that is covering the preview window or click on PM in the status bar.
