I use a Logitech Gaming mouse that allows the use of different profiles while using different applications on your Mac/PC. Currently, I have to go to the devices tab in Parallels and connect my mouse when I want to begin using the profiles I have set up on Windows. Then I have to disconnect the device from Parallels to begin using the mac profiles again. An option to automatically connect the mouse to parallels when the pointer clicks on or hovers over the Parallels window and disconnect the mouse when I click away/hover away from the Parallels window would solve this problem. I imagine this may be an easy feature to create, and would allow other users with a Gaming/Smart mouse to enjoy the full potential of their mouse on a Parallels virtual machine.
