- very good! thanks! Feature request? If the background is dark mode, it will be difficult to see, so I want you to be able to set the background color of the figure.

- very useful to see plainUML in github

- Loving it, it's worked where other solutions couldn't manage a very large drawing. Feature request? Could you make it interactive so that you can highlight a block and press one of the direction buttons to redraw with that directional mark-up. Positioning blocks on larger PlantUML drawings is probably the hardest thing there is about using PlantUML
