I use the Logitech Signature M650 L and really like the mouse, but one limitation is that the custom button configurations (like setting side buttons to Copy and Paste) don’t carry over when connecting to a new device without Logi Options+. Since many users also connect their mouse to work laptops where installing software isn’t possible, it would be very helpful if the M650 supported onboard memory for button mappings. This way, customizations would remain consistent across all devices.
