This is a feedback about MX Keys keyboard from a developer.
The function buttons are placed counter intuitively. I am used having the function buttons in groups of four. It makes it much easier to find the ones in the middle.
The function buttons of MX Keys are in a continuous line. This way it is hard to find the ones in the middle. (Like F7 for example)
Additionally, I am used to having F12 at the end of the button row. But now, I have the volume up button there. Also counter intuitive. I know you did this because your need more than 12 function buttons for alternate functions . But for me, organizing the function button in a conventional way is more useful.
