Would be great to be able to assign any function to any earbud and single/double/treble/long click type. In this way you could potentially have all functions on the earbuds as I have seen on other earbud makes. This would allow you to be able to have anc/ambient toggling as well as volume controls at the same time.. For example, I am used to reducing volume on the left earbud and increasing volume on the right earbud and this would allow that.
