But Dendron is a zombie project.

I don’t mind project being done and in maintenance mode. But I am not investing my time into starting using it.

Getting started page has screenshots broken on AWS.

I took the plunge and don't regret it. Despite the condition of the web site the extension is very useful and relatively free of any annoying bugs.

At some point in time, I'd like to take the time to invest building a custom version of the extension to bump dependencies to access more modern support for plantuml/mermaid diagrams.
