I would love to see a feature where you can change Interaction Cursors for Tiles, Objects, etc.. 🙂
You could also consider doing this for Tooltips, Interact Control Images (when those get added), and Scripts!
examples:
set_interaction_cursor(entity["name"], "cursor_name.png");
set_interact_control_image(entity["name"], "image_name.png");
set_tooltip(entity["name"], "tooltip_text");
set_script(entity["name"], "script_name");
