These days you can just make your own? I can strongly recommend everyone just build their own personal tool...

Or am I missing something?

Here is my personal, Rust based, ultra-fast ADE. Feel to fork an make it your own:

github.com/rjprins/agtk

Or agtk https://github.com/rjprins/agtk

I still use my markdown-modern, and obsidian-style renderer. I read more markdown than I write and for that it works well. https://github.com/rjprins/markdown-modern
