When we go to
Fleet → OurFleetName → Variables
we can see all fleet-wide variables. And how many machine override it.
When you click on this, you get a nice overview of which machine has which value.
We would like the same overview. But without us having to provide a fleet-wide variable first.
So perhaps an extra checkbox: show all variables. Which then would extend the view with all variables from all machines.
Rationale: our application already provides good defaults if these variables are absent. So it’s only of our interest which machines deviate from this by having a variable set.
