If you need a small self contained split view markdown editor (uses a gtk webview, requires an internet for marked.js+katex from a cdn) in GTK+Adwaita. By the way I know about Apostrophe and actually it was the main inspiration for this. I am working on a larger GTK app and I want more software with decent Markdown rendering. This gist is just a small self contained prototype to show off that building this kind of app has become fairly easy today. Comments
