Feature request: un-highlighting should not wait for timer to expire

[articuluxe]

I enjoy the concept of idle-highlight, but for me the highlight needs to deactivate immediately when a key is pressed. If the idle-timer is supposed to represent inactivity, then in theory this state should end as soon as input is received. This becomes even more apparent when I pause my typing, so that the highlight appears, then resume typing continuously: then the highlight will not go away at all.

Thank you.
