mind mapping but cute

If I hadn't put a ton of effort into making my personal wiki lovely I would be all over this. I love how the notes can have "frames" to add little images at the edges -- that took me forever to figure out how to do in Tiddlywiki! I wonder if this could be a useful Trello replacement for a teenager? It has aesthetic bullet journal vibes, but much lower entry barrier to start using / making pretty.
