This reminds me of an iOS app I built years ago (primarily for myself) called Mindscope https://apps.apple.com/de/app/mindscope-thought-organizer/id... - a visual, hierarchical text canvas. Scapple meets Workflowy if you will.

I always loved this freer and more visual form of note-taking so it’s really cool to see a full-fledged, more complete solution with media/images and the whole nine yards. Very cool!
