The placement of the Windows Start key right between the Alt and Ctrl keys means I am routinely pressing it by accident when performing a variety of multi-key operations in various programs. It would be very useful to be able to deactivate it when in selected apps, only when the program is focused (so I could use the Win key normally if I clicked on the Windows taskbar or outside the program in question). I find the functionality afforded by Logi+ for my M330 is very useful, and I think this would eliminate an enormous amount of frustration and wasted time (hitting ctrl-Z because of a messed-up operation caused by pressing the Win key by accident or alongside the Ctrl or Alt key).
