Same boat here, recently discovered tana and its whole model is amazing. It’s fixing most of the things that bothered me a lot in Obsidian and Notion, respectively. I don’t want to go back to a service where I don’t have file-based control over my own data though, so now I’m seriously considering building something on my own that takes the mental model of tana, but implements it local-first based on regular files like Obsidian
