@mashton can you flesh this out a little bit? Is this a partner/user request? What's the path forward for implementing this?

[gigxz]

This was suggested/requested by Nathan for E2CC. I think the desired behavior is to vote on an expense using emoji-reactions on a comment on the expense. Or, people could vote by commenting "approve" or "disapprove" or whatever the options are. We could either modify the existing OC Governance Process or create a new one.

Gotcha - I'm remembering that too from the initial meeting. I'm going to prioritize this as low until we get confirmation from E2C that they actually want this.
