Add the option to show results as a list

The option to display the results as a hierarchy in addition to a mind map. Both have their advantages, but lists make for a neater display at times.

Technical every fetch returns an array of results (a nodeset actually).

So, it's already an array. The graph visualization is just a nice way of showing these results.

If what you mean is having an alternative "table view" (for example, in a different tab - pretty much as in Neo4J Desktop), then it's absolutely in my to-do list. Perhaps one of the next few features coming! :)
