So funny this pops up. Last few days I've been wanting a new notes app that wasn't using some database and was files based, plus I feel like other notes app rich text copying and pasting notes can be a mess. Plus a bit unorganized so wanted a new notes app and just copy things over as I need. This one looks pretty prefect for my wants.
I also like how it has both folders and hash tags too instead of being forced to pick one over the other.
Just curious if you had tried Obsidian (https://obsidian.md)?
I'm still looking for something with a cross-platform GUI that I like as much as I liked Obsidian.md - but with the same sort of arbitrarily nested hierarchy (with TODOs and the like at any level) and the ability to adhoc rearrange my notes like org-mode provides. The Emacs/org-mode level of customization would be nice, too.
Trilium Notes ( https://github.com/zadam/trilium ) was also a good contendor, but not having a text-content-first focus made for some frustrating experiences of data corruption, and testing data export of my initial trial run was messy as a consequence as well.
