Hello. I tried to download this but the external site is down. Plako do you still have the .DMG file? It is "QuatioObserver_1.1.2.dmg.gz"

No mountable filesystem in the DMG file so I cannot use this!

You can achieve it by opening Monitored Items from File menu and by dragging the mounted dmg disk in the item list...
