I would like to export the note as a PNG/JPG image so the table will be included.
Exporting as a PDF is the current alternative, but I find images easier and simpler to email because images can be inline and images automatically shrink to the screen size.
I think the easiest option is to screenshot it - works on desktop and mobile.
I also would like to export my html note as .png image with transparent background. Transparent background is not possible with just screenshot. I use currently some chromakey as a background and then remove that color, but it's not an ideal solution.
