Hi Chris,
This worked very well for me, I already had some git hub pages so just added another directory https://git.johnj.info/tiddly/
Took a few goes to get the settings to stick but I got there. I also found if I had two browsers open saving failed. Get the odd save error, but it seems to sort itself out in the end.
Not sure what I am going to do with this as I’ve a couple of other Tiddlywikis, but it is fun to play with.
Awesome! I’m still tinkering myself to figure out what works best for what. Glad you managed to use the notes to get things working. I like that featured photo when it opens up btw.
