Hi, I am a new TW explorer. maybe i can help
Tiddlers json just need “title” field, then “text”, “tag” are show and use by UI.
all other fields are yours
Not sure about the question
What would be the average size of your trials data, what kind of data structure?
Maybe you could consider using “ipfs” to reduce TW size. This way TW can be overloaded Tiddlywiki and the IPFS “Video Wall” Experiment
