Would love to see some external way for storage blocks to indicate when they are full. Maybe changing color, or something like that. A real chore to go clicking on each to see what it's status is.

Or even some way to see what my total usage of the combined storage blocks are.

I don't think this is needed

How do you know then what your combined storage capacity is and how much you are using?

Maybe if you are not able or willing to implement something like that, you might know of a solution?
