Very nice!

[grant-davidson]

Are you planning to add the usage instructions to the readme?
It's probably worth prefixing your current instructions with "If you export to html and then open the html file in Chrome...." or similar

[dai-shi]

good point. do you have an idea to improve the description in README?

[grant-davidson]

At some stage we should probably add some documentation that is accessible from the app itself (similar to or replacing the excalidraw help) but I think the pull request link is ok for now.

Thanks!
