Please finally allow assigning host switching to the top buttons — the same function currently handled by the bottom button. Sometimes the Flow feature glitches: the mouse jumps to the next host, but the MX series keyboard stays on the previous one. When using Ctrl as a modifier to trigger that function, you can’t switch back, and you're forced to physically pick up the mouse and press the button. There’s a DPI button that virtually no one uses — let us assign host switching to that instead.

On Windows, I managed a workaround by assigning the DPI button to emulate a Ctrl keypress, which lets me simulate keyboard input. But on macOS, there’s no way to assign a “plain” Ctrl — it always becomes ^Ctrl, so this workaround doesn’t work there.

The Flow feature without a dedicated button causes too many accidental triggers and isn’t convenient. Worse, it suffers from the same bug: the keyboard stays on one host while the mouse moves to another. I once accidentally revealed my password this way, thinking the keyboard had switched with the mouse. Not critical — but definitely unpleasant.
