My attempt to somewhat imitate one aspect of Dynalist in TiddlyWiki: Create a list of compact notes with hashtags, then filter search by hashtag to show only the items with the same hashtag. There are several advantages to doing this in Dynalist. But doing it in TiddlyWiki makes it easier for the results to be printed cleanly, and the notes can have anything in them that a tiddler can.

Just showing this for feedback for me, and any inspiration it gives you for projects of your own.
Thanks to @EricShulman for the search filter!
