We probably want to have a system that allows storing arbitrary key value pairs (probably both of type string initially). And then allow visualizing them as an info text component. The counter component can then use those to represent its inner state. The Run Editor can show them in the Metadata section. I'm guessing these variables should also have other information such as whether they are transient or are kept across attempts and whether they are read only in the Run Editor. Auto Splitters and components can provide them.
