Thanks for your long and thoughtful reply!

Matrix is just a visualisation tool, I never actually found a practical use for it other than looking cool.

The decomposition feature is at the bottom of the page below the generated HTML. It's the text box with "隹" and a Search button. Clicking Search will show the 2 parts of the character, and all characters that contain that radical (䧶, 䳡, etc), and all multi-character words containing that character.

Clicking any of the related characters (or numeric codes for radicals that don't have a Unicode representation) will then show the genealogy for that character.

If I ever come to Berlin then your meetup sounds fun! I'm pretty far away though; I live in New Zealand now.

All the best with your learning, I hope you keep making progress!
