Feature Request: output viewport

[jancassio]

First of all, thanks by making this project, it's really cool.

It is a question but you can consider it a feature.

There is a way to open a window or something else to output some UI on that?

For example, I would like to add an <canvas/> element, then, add some graphics on that.

Thanks,

Thanks, this is certainly a future possibility.
