turn to no sector in sector sensor, when not in use

[Xyz00777]

Describe the bug/feature request (not sure)
not sure if really a bug or feature request.
I would really like it if the sensor for the section you are in at the moment would turn off or no input or something like that when the brush turns off/goes into idel for more than (i dont know) 3 seconds?
Because of that the last sector im brushing is getting showed as the whole time until i brush again....
