Hi, I’m here as a user, not as a developer. As a user, I would love things like table support, and, as I have written previously, some way to write lists without having a list indicator character for every single line. CSS support (e.g. a shorthand for creating a with an associated class) would also be great for e.g. control of text color and fonts.
And here’s another: I love JIRAs basic support for emojis and icons. I understand that this may lead to additional requirements like hosting images or embedding a font or something (my insight into CSS is shallow), so I’ll not suggest how to implement this. However, I assume emoji support would be welcome for certain user groups. In my current use case, I would like to include JIRAs (i) and (!) for icons in Markdown-formatted log files that are shared between users and developers.
