feat: use nodeCounts to show actual maximum number of nodes at the filter option

> 🔔 *NOTE*: we need to merge differentiation first!!!

The filter option was a bit confusing, as it never showed the total number of result. This PR still doesn't show the total number of results, but it uses the nodeCount from the differentiation branch to show the total number of nodes in the result. I think this is a bit closer to the expected behaviour.
