I had trouble finding where the icon selection was also. Perhaps it would be easier to find if you separated the sound and icon selections, or even separated the sound and icon selection into a new main menu item - they are under the notification menu now, but I don't consider them notifications, so I didn't look there at first (new main menu item: Select sound and icon files)

There is an unpublished program update that lets you change the icon https://sourceforge.net/p/micmute/tickets/31/
