@mjbvz it would be cool if our markdown renderer supported this.

Note for later if I want to add support in the extension: https://emojipedia.org/shortcodes

[mjbvz]

This extension adds support for the markdown preview: https://marketplace.visualstudio.com/items?itemName=bierner.markdown-emoji

However this rendering comes from core, so we're unlikely to add support there. What you could potentially do is do a prepass to replace the :emoji: in the markdown you pass to core
