Would also be very easy to add a switch that turns the indicator lights on while pressed. At least any indicator lights I look at already require me to be at arm's length from the device to discern which light is which.

Note that this is not one of those things that sound simple but would complicate the design a lot. It's literally just adding a switch to one of the line supplying power to the lights. It can be done completely modularly -- probably even hacked into place after the fact.
