Custom Emojis uploading

Hello Codans!
I was wondering if it would be possible to upload custom emojis one day, a bit like in Slack.
As I’m more and more using emojis on document titles, it would be a great way to have quick glance and recognise families of documents (with custom emoji logos for example).

I support this. We use Slack at work and definitely make use of the custom emojis.

That said, I assume having more robust image features could solve some of the/my use-cases for custom emojis.
