currently, the volume meter in a storage facility of a PI is colored blue.
If several items are stored in here it is not so easy to identify with an eye blink which material is occupying the biggest volume size.
I was thinking that it would be nice if you would click on an item stored in the storage facility that the amount of volume is colored in a different way than blue(which is the total volume).
This way, you can have a rough estimation of which material is consuming the most volume in the storage facility with a blink of an eye.
