Chanced upon this very open source Taskpaper-like Mac app that works with Markdown files (in your folder of choice) as WYSIWYG (like Typora) and offers tags, backlinks and workspaces.

A downloadable webapp that works with Chrome or Edge (but not my main Chromium browser, Brave, for some reason, or Firefox).

The Github page shows it's being regularly worked on.

The dev who created it had been managing his plans with a text file then ran against its limits so he created the app mainly for himself, then kept going.

Thanks a lot for sharing this. I've spent a lot of time browsing around on the related sites and it looks like it has a very bright future, if the developer continues as he has for a couple of years now.

It seems to be a JavaScript coded project which runs in Chrome and some? other browsers. You mentioned Apple related platform, but as far as I can see, it should work on any PC platform on which Chrome will run. I saw some mention of trying to use it on mobile, but seemed it was not optimal there, yet.

These are some of the highlights from the web page:
Fully offline
No install
Open source
No data hostage

I only mentioned the Mac because the screenshots are all macOS. But yes, the Getting Started file mentions equivalent key commands for Windows (but it's about the only place I saw any mention of Windows).

Thanks. Pretty slick. On first blush, it's easy to learn and use. It's a kind of markdown-ish scratchpad that's pretty good for managing notes. It feels a little like a locally hosted Dynalist. Non-proprietary, uses existing note, if needed (although I haven't stumbled across how to point it to a file system directory). What's missing for me:

- limited to three levels of header? (No, you can use markdown #, it's just not a pop up choice)
- no hoisting (that I can find)
- no word count (more of a writing tool issue, but I need it!)

Good crimping fun!
