ANT+ button turn green when 'active'

The GPS and Live Tracking buttons both turn green when they are 'active', why not the ANT+ button?

How about it turns green when it does connect to a device. Then, it should turn orange when any one of the ANT+ devices that have once been connected for this recording session is now not connected? (And green again when all previously connected sensors are again connected).

Is this a problem for the BTLE sensors button also?

I'm not much of a sensor user, I only use a HRM strap, but I was expecting some audio and/or visual feedback from Locus when a sensor is lost, much like GPS?
