Is this similar to the idea of voting on issues?

Similar but a) with more nuance, b) github is using them for comments (including pull requests); we could also use them for actual commits (I definitely want to ♥ those sometimes!), and c) 🌭.

I accidentally filed a duplicate ticket in #2263, but here's a proposed implementation that I suggested in my ticket.

Implementation

1. User mouses over a + button near edit and delete buttons in an issue comment
2. User given emoji search bar (similar to typing : in an issue now)
3. Searches and selects emoji "reaction", e.g. :100:
4. In opposite side from react/edit/delete buttons, a display of the emoji with a counter for number of times used, e.g. :100:x2

This is pretty similar to how it works in GitHub already except being able to select emoji instead of a limited few.

Commit 59889e50 fixes this issue

I would add a reaction, but I guess it's not deployed yet. So we'll have to settle for \o/
