[REQ] better hotkey action

[sunaneko-1324]

sorry for bad english! i used machine translator.

Is your feature request related to a problem? Please describe.

1. when change the ambient sound volume to hotkey, an 'ambient sound is on effect' sound occurs.
2. Display battery pop-up shows only battery remaining.

Describe the solution you'd like

1. only change the ambient sound volume.(same as noise control panel)
2. I hope there is additional information in the display battery pop-up. (ex : display current state in noise canceling mode/ambient sound mode...)
