If I swap left/right buttons, the setting applies to ALL mice I have connected to my computer. Your left-handed mouse uses hardware-swapped buttons and I can't un-swap them (so that left is left and right is right, which is what I want). If I change it in Logi Options+, the swap also applies to a different mouse I have connected. Please only apply the swap to the device I'm configuring, instead of the entire OS.
