Feature request: Mixer pix for Inputs & Outputs

The new pictures in the mixer are great. Really makes visually finding a specific channel much easier. However I was disappointed to find I couldn’t add pictures on the input and output channels. Clearly not a major issue, but it would be nice to have and I suspect easy to implement. One other thing, I couldn’t find a way to remove a picture other than replacing it with another - so I just made a black square to “delete” a pic.

Also, helpful hint - it’s easy to snag pics of specific items from the product pages at your favorite online music store.
