Feature Request: popup with separate Speaker and Microphone volume sliders

[plevesf1]

I would like to suggest adding a small popup window that provides quick access to Microphone volume alongside the Speaker volume.

Use case

Volume² is very convenient for controlling the speaker volume, but it would be useful to have the microphone volume available in the same place.

For example, I would like to be able to press a hotkey or click the Volume² icon and immediately see something like:

Speakers: -----?----
Microphone: ---?------

The microphone slider should control the Windows recording/input volume in the same way that the speaker slider controls the playback/output volume.

Possible additional features

It would be even better if the popup could optionally show:

The current speaker volume percentage
The current microphone volume percentage
A mute/unmute button for each
The currently selected recording device

I believe this would make Volume² even more useful for users who frequently switch between adjusting their speakers and microphone.
