When switching XFCE workspaces, theres no default notification that tells you which workspace you are on. I have a little script to get around it using
Enable extra monitors or dual screens for Debian xfce in VirtualBox
For any excessively tidy people, windows snapping is a must; Xfce is a great desktop environment that provides such features. By default though, it seems that only horizontal snapping works and you'd have to tweak the settings a bit to make vertical snapping function as well.
