Basically what I need is an information organizer. I did come across Tiddlywiki a while ago, but it was when I was very busy so I didn't give it much thought
The way you could layout information in OneNote I found especially helpful for organizing and planning TTRPG sessions, so I have real specific use case that I'm trying to replace. I could definitely bend Tiddlywiki to do that.
Basically I want an internally linked document that can support graphics and text.
