Great, happy to hear that!
By the way, regarding tooltips on the node map, it is not as straightforward as for the other tooltips in the kit, since the nodes are not widgets, and thus don’t have a built-in implementation for tooltips.
You would have to make your own my creating a new widget that follows the mouse and turns visible/updates appropriately when it detects that the mouse is over a node, such as through a line trace. Certainly doable, but takes a bit of work.
Have you considered doing what many games in the genre does and just use a map legend?
