+- `mic` is a special option to control your microphone's input level _(uses the default recording device)_.
+- On Windows, you can specify a device's full name, i.e. `Speakers (Realtek High Definition Audio)`, to bind that device's level to a slider. This doesn't conflict with the default `master` and `mic` options, and works for both input and output devices.
+  - Be sure to use the full device name, as seen in the menu that comes up when left-clicking the speaker icon in the tray menu
 - `system` is a special option on Windows to control the "System sounds" volume in the Windows mixer

+- All names are case-**in**sensitive, meaning both `chrome.exe` and `CHROME.exe` will work
 - You can create groups of process names (using a list) to either:
     - control more than one app with a single slider
     - choose whichever process in the group that's currently running (i.e. to have one slider control any game you're playing)
