Confusing behavior of brightness keys with regard to persistance

[ids1024]

Setting brightness with brightness keys is not persistent. But setting brightness in the Configurator is. This results in confusing behavior.

Normally brightness set by key isn't persistent:

• Adjust brightness using key binding
• Unplug keyboard and plug back in
• Keyboard brightness is reset to previous value

Except if you open the configurator:

• Adjust brightness using key binding
• Open and close keyboard configurator, without changing anything
• Unplug keyboard and plug back in
• Keyboard brightness has value set earlier, since configurator send command to persist it

This isn't a huge problem. But it's an inconsistency that should probably be addressed. Not sure how we want to address it. The brightness keys could save the setting persistently. Or there could be no persistant brightness setting. Or there could be a separate persistent "default" brightness in addition to the current value.
