Annotating decks with SVG

    • Use a data URL. You can copy the data URL from Method under File > Save.

So, it wasn't broken per-se, but it kind of missed the point of using a GUI editor.

Then I hit on the idea of using lots of small external SVG images using the HTML <img> tag. This would allow the SVG images to be positioned within the GUI just like other images. Unfortunately, in
