@juliushaertl what is the markdown code to generate a checkbox?

The use of 2 square brackets with a space between is how the old editor did it (and also I think github MD) [ ]

Tried it so, doesn't work for me.

Testing on v1b1, the card view shows a check list when I add something like

[ ] an item
[ ] another item

(at this point the card shows a ✅ 0/2)

But the view of description continues to show just [ ] an item and the only way to check one is replace the space with an x

I tried that, which makes it autolist while editting (useful :) ) but still doesn't render in a way that allows a user to mark the check box by clicking it.

This is what this pull request implements for the preview mode. However there is still a small issue, since the library we use for checkmarks in markdown only supports list style checkboxes - [x] not independent ones [x], so we need to adjust the regex for the card badges as I don't see a way to support both right now.
