The Pen Flicks are gestures, to help you easier to copy, paste, scroll etc, they are very important gestures for everyone that is using a Wacom Pen.
Are they forwarded from the Host Windows 8 to the Guest Windows 8 in this release of VMware workstation?
Can I copy and paste easily inside programs that run in unity mode?
Will that ever happen? like in VMWare Workstation 20 or 30 
?
