The most interesting thing about this for me (as somebody who already uses TiddlyWiki and is just curious about features) is the ability to easily make flashcards from components of your zettelkasten.

I already use Anki heavily for studies that require it but integration would be even more powerful - copying text snippets from a zettelkasten to Anki is unsolving the problem that knowledge-map systems are trying to solve. I’m surprised I haven’t seen a feature or plugin like this for Roam/Obsidian/TW.
