The PlantUML integration is excellent (thank you). I have set the default open and close tags to

```plantuml

and

```

respectively. It reads better when using tags other than @startuml such as @startwbs, @startmindmap, and so on.

I'd love to see live rendering in the editor. For now, I'll try to set it up so that clicking on the finished image launches the plantuml server's interactive editor.
